I played this game last night without a hitch then this morning I loaded it and it stopped loading and froze at the ESRB ratings screen ! I then turned off my PS3, turned it back on ejected the game, signed out of PSN re-loaded my game and it worked perfectly until I signed back into the PSN then it froze on the "End Of Game" screen I'd finished playing while signed out of PSN !
I then proceeded to delete Game Data Utility files and restarted the game while signed into the PSN and again it froze in the exact same place, the ESRB ratings screen ! I then re-started my PS3, signed out of PSN, reloaded the game and again it loaded just fine !
Any ideas what's going on ? All other games work fine !
