My brother bought this game when we first got our PS3. This game is autosave and when he turned it off and turned it back on again on the career menu said 'New Career' and had obliviously not saved. this has happened 3 or 4 times. Is it a corrupt disc or something? Please help if you can.

no, it's just a glitch, you're data is still there. I usually go back and forth between the offline/online modes until I see continue game. Unfortunately they didn't bother fixing this when they released a patch a little while ago.

Thanks. I searched around on the net and it seems to be happening to a few people. I solved it by taking the game back and swapping for a new copy of Ghostbusters and all the save data was there and it now saved perfectly. The problem I think is corrupt data on the disc.
