If you are experiencing issues with Pro version when you bought it and still getting Message Box to "Buy", it means that you have Lucky Patcher or similar app installed, which tries to modify app and interfering with License check from Google.

Security is one of the main goals of Muzecast/HomeDJ to prevent stealing user information, music, licenses and password.

Muzecast/HomeDJ has proprietary encryption algorithms, which are redundant and all branches of the security check and encryption should return the same result, otherwise access will be blocked to prevent private user information to be stolen.


Muzecast has multiple layers of protection by encrypting encrypted licenses, user names, passwords, security tokens with dual or triple security encryption, which is proprietary.

Some users reported, that all of the sudden Muzecast purchased application started popping up Message Box with 2 buttons: "Buy" and "Exit", prompting user to purchase application again.

This was directly affected by Lucky Patcher (thank you for one of the users finding this out). That is Muzecast protection in works. Lucky Patcher was unable to unsecure application and just corrupted it preventing it from run.
