Had the same problem with Episode 2. Blogs report game is available, but my game will not update. Have rebooted several times, closed all apps, etc. Still, no luck.
Telltale Games, I am clearly not the only person with this problem. Would you please post a sticky message acknowledging that this is a known problem and suggesting solutions?
I don't want to delete and reinstall because I will lose all my progress and decisions in the game.
