Recently, I come across such an issue and fixed very quickly. Here is how you can fix licensing error of purchased apps and games on Android phone and tablet. Assuming that your phone is connected to active internet (Wi-Fi or 3G, or any data connection), and then follow the below steps. Go to your phone Settings and choose “Account and Sync” option. Tap the account that is connected with your device and Play Store. Enable the option “Sync App Data”, if it isn’t enabled. Probably, it will fix your issue.
