now it's the same for every level, so now I'm just stuck at kid buu... wow this game is sucky, they really need to update it.

I got the game on xbox 360 yesterday, then today when I got to mission 37 (The fusion fighter) whenever it gets to 5 minutes remaining, it automatically says I have lost, excuse me if I'm missing some key thing but on the pause menu it just says defeat Gotenks and Piccolo. Any ideas?

Note: I have checked, my disk isn't scratched in any way, or laser burnt, and I bought it brand new.
