[quote name='tgk2044']Unless you're sure it's the disc, try clearing the hard drive cache, by selecting it in the memory menu of your 360 dashboard, then pressing X, X, Left Bumper, Right Bumper, X, X. Then select yes. I've had to do this for some other games that gave me this problem.[/quote]
omg I went to four different stores asking about cleaning the disc today and then came home and read this, took the advice and now it works. WTF WWWHHYYYYY
EDIT: and then my internet started working again and it downloaded an update for rock band which made the game freeze at the exact same spot again.
