So I tried playing Injustice this morning and it kept freezing the Xbox whenever I put it in. So assuming it was the Xbox, I tried some other discs which worked fine. I checked to see if Injustice was scratched, but it's still in brand-new condition. For some reason I tried it without signing in and it plays fine, but if I sign in, it freezes. Could it be that my save is corrupted somehow? I don't really want to have to play it unsigned in all the time and the Batgirl DLC is out soon.
