Corrupt?!?! Noo!!!!!!!!!!!!!!!!!!!

[Dyne]

DAMN THEM! DAMN THEM ALL!

I came back from dinner tonight (birthday lobster hehe) and I turned on the cube. Everything booted up fine. Then the message from HELL came up:

Data corrupt. Must delete files. Ok?

I said no like fifty times and it still brought up the same message. Does ANYONE know why that happened? I'm using a Memory Card 59, first party.... And I'm bloody pissed. The only thing that really was a highlight for me was I was finally able to use my MUSASHI, and my brother and I both found MAGs offline. But, nothing else was big, just played with some people. It totals to around 44 hours so far in a period of 3 days... those files were special. I lost like ten Rares, five of them g-class ;_;

Has this happened to anyone else? If so, any suggestions so it doesn't happen in the future?
