FAQ & Support Guides

Incompatible Devices
We are aware of a small number of compatibility issues caused by a 3rd party database library that we rely upon across our product portfolio, which may cause crashes on a small number of specific device / firmware configurations. We have contacted the library vendor regarding the issue and withdrawn our app listing on the Play Store for the affected devices meanwhile. This is to ensure that new users do not purchase and experience the same problems while we attempt to resolve the problem. As the code responsible is 3rd party source code, we must wait for a fix from the vendor before it can be deployed in our applications.

Currently affected devices
Samsung: crownlteks, dreamqltesq, greatqltechn, hero2lte

Other known issues
LTE: NX591J - play services compatibility.

Problem
You are receiving "Unable to install to device usb or to memory card" when attempting to install the app via the Google Play Store and Android does not complete the installation.

Solution
Open the Android app drawer (where your apps are).
Choose 'Settings', then 'Apps' (some devices may be 'Applications → Manage Applications' or similar).
Choose the 'All' tab and select 'Google Play Services'.
Press 'Clear data' followed by OK.
Press back and this time select 'Google Play Store'.
Press 'Clear data' followed by OK.
Go back to Settings and this time choose 'SD & Phone Storage' (some devices may be 'Storage' or similiar).
Press 'Unmount SD Card' and then 'OK'.
Open the Play Store app as normal and try to install the purchased app.
This time it should successfully install.
Go back to 'Settings' → 'Storage' and press 'Mount SD Card'.

If you're still unsuccessful, please contact us via the contact page.

Problem
Your purchase is stuck on Authorizing when trying to purchase the application via the Google Play Store.

Solution
Please log in to your Google Payments account at https://wallet.google.com and verify that your card payment for the order has been authorized.

- If the authorization has failed you will need to update your card details to allow the payment to be taken successfully.

- If your order has been placed under 'customer review', you will need to wait until Google's automated security checks have been completed - this may take several hours.

- If your payment authorization is showing as successful, but you still cannot download the application, you may be experiencing an internal Play Store app problem.

Problem
You are being prompted to perform a license check at every launch and going online to retrieve a cached license does not provide any offline access afterwards.

Cause
If you have installed the application manually from an apk installer or from a backup application, rather than via the Play Store, the offline license file may not be issued or not may be validated correctly.

Solution
Ensure that the application has been installed through the Google Play Store. If you have previously used patching tools to modify the Play Store or Android or application frameworks, please ensure these modifications and tools are fully removed first. Unfortunately we are unable to manually issue, or alter licenses, as these are managed by the Google Play License servers. These restrictions are sometimes temporary and user account specific.

Problem
You are receiving a "Download unsuccessful" message when attempting to download an app via the Google Play Store.

Solution
Restart your phone then try downloading the app again.
Confirm that there is internet connectivity on your device.
Wait 10 minutes and try your download again.

Problem
You launch the app and the loading screen animations run, but then the app appears to be stuck showing just the logo and "loading...".

Solution
Ensure you have a functioning internet connection on your device and launch the app. Please wait for 60 seconds. If no progress is made after this time then please follow the steps below:

Open the Android app drawer (where your apps are).
Choose 'Settings', then 'Apps' (older devices may be 'Applications → Manage Applications').
Scroll across to 'All' and select 'Google Play Services'.
Press 'Clear data' followed by ok.
Press back and this time select 'Google Play Store'.
Press 'Clear data' followed by ok.
Restart your device and try loading the app again.

Problem
This occurs when the app is installed on the storage card, but the SD/storage card later becomes unavailable. This may occur when the SD card is removed or corrupted, or when the phone is connected to a PC in disk mode.

Solution
Please ensure that your SD card is inserted properly and that your handset is disconnected from the PC while using the app. If this does not resolve the problem, restart your handset then uninstall and re-install the application through Google Play Store.

Problem
You try to load the widget via the Android app drawer, but all you see is a 'Getting started' window with a close button.

Solution
Android widgets cannot be loaded by clicking the icon in the app drawer.

Instead you must long-press on your Android desktop and select 'widgets', followed by 'crystal widget' 'indoor plant widget' or 'tropical fish widget'. Multiple options will be available, such as 'Crystal Widget 2x1' etc, these indicate the size of widget. On newer versions of Android you will need to open the app drawer, then select the 'widgets' tab at the top and then select your widget.

Problem
You have previously purchased our software via the Google Play Store, but have since changed your phone (or moved to a different Google account). The Play Store is now asking you to purchase the app again.

Solution
Your licence/purchase information is tied to the Google account that was used to make the original purchase, therefore all you need to do is add this old account to your new device. You can do this by following the steps below:
Open the Android app drawer (where your apps are) and choose 'Settings'.
Find your device's 'accounts' section and select Add account.
Select Google on the account list.
Choose add an existing Google Account.
Follow the sign in instructions and enter your original (purchasing) account details.
Load the Play Store and select your old account (touch the profile icon on the top right to view the accounts).
You should now be able to install the app again through the Play Store without re-purchasing.

If you have previously purchased our software via the Google Play Store and would like to install it on to other devices that you own, you can do this by simply adding the Google account that you used to make the initial purchase on to your new device(s). You can then install as usual via the Play Store without needing to re-purchase it.

How To
Your licence/purchase information is tied to the Google account that was used to make the original purchase, therefore all you need to do is add this account to your new device. You can do this by following the steps below:
Open the Play Store and touch the profile icon on the top right.
Tap the down arrow next to the existing account name and pick 'Add another account'.
Follow the sign in instructions and enter your original (purchasing) account details.
Load the Play Store and, if necessary, select your added account (touch the profile icon on the top right to view the accounts).
You should now be able to install the app through the Play Store as usual without needing to re-purchase it.
