Sonic The Hedgehog 4 (Android) Help Please!

[josh893]

I downloaded an apk file for SotH 4 Ep. 1, and it's running pretty good. Now, I need help with Episode 2. I downloaded an apk file last night and installed it on my tablet. When I opened the game, it said something along the lines of "Failed because you may not have purchased this app". Does anybody know why this is happening? Am I missing some files? Also, if I am missing any files, could somebody provide me with said files?

Also, if this is in the wrong place, I apologize. I've never really posted here before.

Sounds like it is missing something that makes it active or they have copy protection in it that looks for something you don't have either way that copy you have has not been cracked

check the documents that you got with the file and see if it has any specific instructions to get it running

There were no documents, just an apk. Anywhere I check, it's just the apk. I pretty much gave up.
