I am currently on day 2 of my game - PS3 platform - playing Welcome to the Jungle mission. Have cleared tower and now heading to Phsyco waypoint. Have cleared minefield and picked up ammo next to trainwreck. As soon as I step through trainwreck - game freezes!! Total lockup with no commands from buttons being acknowledged.

Shutdown of system and restart - normal PS3 message Not shutdown properly and system check and rewrite of files and restart!! Exactly same thing happens again.!! I have deleted game and re-installed - same result. Have checked disc - no physical damage visible. System itself is fine as I play Far Cry 3 and COD Black ops on it daily.

I can go to any point back in the mission with no adverse effects, but as soon as I try to go forward past that point - FREEZE!!!! Have tried all other ways and places to go forward - same result!!!
PLEASE tell me what to do???????????????
