I deleted the other files and loaded the one you provided, it worked first try. When I paused the game and went to go back into the song, all the chords had disappeared. I shut down the game and now the exact same problem is happening...freezes as soon as the amps drop into the screen.
I've installed the proper files and followed the instructional videos on this site. My songs show up in my learn a song list, they start just like every other song, but when it starts, all i see on screen are the amps and then the game appears to freeze....suggestions?
