Okay... I have no idea where else to put this, so I'll put here...

I was playing Dissidia this morning, when all of a sudden, my PSP turned off on me... I didn't know why, but anyway... I turned it back on, and turned on Dissidia again...

When I went to start playing, I found that my game data was deleted somehow. Why did it happen, I wasn't sure.

So then, I checked the game datas on the PSP, and I found out that it was corrupted.

And now comes my question...

Is there anyway I can recover corrupted data?

I was really far into the game, infact, I beat the story mode, and even had Cloud on level 100, and accomplished alot of accomplishments, I don't want to have to lose all that. So can anyone help me?
