Licensing error

If you get an alert saying "No valid license for this app.", please do the following:

  • Be sure that you downloaded the app on Google Play
  • Check your internet connection : the app needs a working internet connection to check the licensing status

If both previous conditions are met:

  • Click several times on the "try again" button until the app in unlocked

If you don't manage to solve the problem, please contact us at and tell us which email is linked to your Google Play account (login email).
