Google Play Store could not verify your license message


Applies to the following products ONLY:   Crystal Guide Pocket EditionCrystal WidgetGem Carat Weight CalculatorTropical Fish Guide Pocket EditionTropical Fish WidgetVet Nurse Quick Reference

warning All verification failures are logged and audited.



Problem

You are trying to launch one of our products (from the list above) and receive "Google Play Store could not verify your license.  Please ensure that you are signed in to the Google Play account that was used to make the purchase and try again.  If you have not obtained this application from Google Play, please consider supporting the developer by purchasing it below".


Solution
To verify that the app has been purchased through the Google Play Store, our applications ask the Google Play Store for a digital license certificate.  If no certificate is found for the Google account on your device, this message will appear.  If you have purchased the application via the Google Play Store, please ensure that you have logged in to the correct Google account on your device (ie. the account that was used to make the purchase).

To do this:

Open the Android app drawer (where your apps are located).
Select 'Settings', then under the Accounts heading select 'Google'.  Older devices may be 'Accounts & Sync' or similar.
Ensure that your account login matches the account used to make the purchase.
If the account is not listed, select 'Add account', press 'OK' and follow the prompts.
If your purchasing account is already present and correct, please contact This email address is being protected from spambots. You need JavaScript enabled to view it. with your order details for further assistance.

Note: After adding an old account you may need to load the Play Store, swipe the left hand pane out and select your purchasing account.
