at first it was only one map. nuke town. but now its more and more. when one of these maps starts to load i end up with it like 95% done b4 i stop hearing other players. then it slwly loads the rest fot he way on the bar. and just sits there, the little wheel keeps spinning at the end of the bar but it doesnt say loading players or anything. it just sits there spinning. i have to exit the game via the dashboard button and restart. sometimes the game will also say the disc cant be read when i start it up again.now im down to just firing range as the map it doesnt freeze on. altho i whiped the disc clean with a damp cloth i can now play fireing range,jungle,and wmd. but still all the other maps just freeze. also like just now i went to my dashboard menu from the game and went home. it turned my console off. sometimes when the map freezes the whole console freezes aswell. any ideas on how to fix this? preferably soemthign that wont cost me as the console and game were already costly. and i bought them both brand new from the store.
