I will have to think back about what I had to do to mine.
I have been able to run all three AC games with no problem.
It may have been COD: BO that was giving me the same issue as you.
Oh, hey.........is this a game you d/l'ed?
If so, it may be a patched game.
I patched my BO game while still on 3.41. Worked perfect.
After bumping up to 3.55 and MultMan, I started getting that message.
I don't recall which two files needed to be replaced (someone here will let you know), but after I put those two files back in from the disc it worked perfect.
One of them was the param.sfo.
It may be as simple as tracking down the two original files.
If the name of the other file is not posted by about midnight tonight (when I get back in front of the PS3) I will go in and look for the name of it.
Good luck.
I would much rather go to my grave not needing my gun, than go there wishing I had it.
