PS3 CORRUPT GAME (Help!!)

Hi I just played Kung fu rider yesturday, for half an hour. After when I exited the game I went back to the ps3 break menu and it showed no other game on my external hard drive. So i thought my hard drive was corrupted

So then i used Getbackdata to get back my games it took like 12 hours, after that finished i loaded my games back on to my external and it showed up with no picture and no game title on the ps3 break screen only the ps3 Game folder eg BLES-7002. Then i press play and it says its corrupted

So I put the external back on my Computer and open the game file and the PNG file was not recongize

What should I do? any help appricated
thanks

kung fu rider, the pirated copy strikes again. this is what you get for downlaoding a small rip of the game.
