why is this the only game i constantly freeze on. i tired of racing for hours and then my game freezes before i leave the lobby, thus not saying my data. i even clean the disk frequently but it doesn't help. i think it has to do with the last update because it didn't happen when the game first came out so polyphony digital, if u can understand wat im saying then can u PLZ fix this problem. it is really starting to piss me off
