Anyway i was trying to play campaign and it didn't work i got the "failed to load content" and "game failed to start" so iv been playing with it the last few days and its messed up, EVERYTHING works BUT campaign, so i got a new disc and guess what, same problem. also i can fully download it to my Drive, it gets to about 40% then says it cant read it, and im pretty sure its not my xbox, its only a few months old and everything else plays fine on it.
