As normal I've downloaded a load of boxers to fill out the roster. I was making my way through Legacy Mode with Juan Manuel Marquez, had about 15 fights when I got asked to step in and fight Amir Khan. However when the loading screen comes up pre-fight, the game keeps freezing. Anyone else had this problem?

I'm not sure whether there's just problems in general with importing created boxers into legacy mode, or whether it's my Xbox being a dick. It's a bit of a pisser because I was on a 10 fight win streak. I've downloaded an entire flyweight division as well, I was looking forward to tearing it up with Khaosai Galaxy after my Marquez career was over. If it's going to keep freezing then I won't be able to.
