I downloaded TTR a couple of days ago and it's been working great. However today when I downloaded and installed the Guitar Hero Mod, I started running into problems. I can open the application just fine, but when I click iTunes Library to choose a song to play, the game pauses for a couple seconds, then returns to the iPot home page (springboard). I uninstalled TTR, getting rid of the Guitar Hero mod, but I'm still having the same problem. Anybody else run into this?? Thanks in advance.
