Why does the game keep telling me start up error?

Sounds like a disk read error on your actual system, not the game. Might wanna try out a different game or something first? Then call sony.

Also what you would also want to try is delete any of the installed information the game put on your system.
So under your game save folder, delete anything [since you haven't started, its ok] Also delete the install data, try and run/install the game and see what happens. I've had a bad install on another game before, the above worked.
