I recently downloaded both the Assassins Creed II and Crackdown like everybody else on Xbox Live, but every time I go to play either one they both end up freezing on me like 10 minutes into the game. Is anybody else having this problem? I have already tried deleting and re-downloading them both and I have never played Crackdown so it's not my game save. Does anybody have any suggestions or anything?

Thanks,
