issues with Darksliders data corruted

when running the game from xmb it says game data corrupted , delete and try again. there is no data in the game data folder.

MM = 2.01
kmeaw 3.55
us disc 30320
game is split so from external, let MM do its thing on setup up files. try to play it and it give the game data is corrupted delete and try again. Moved game to internal hdd same result. On both ran fix permissions again same thing. It shows up on the working list so i think it may be a game issue?

btw when MM installs split games to play from external where does it put the files?

TIA.

It puts them in games usually. What size does MM say it is?
