Screen of Death

[FireKing]

Ok so i started using modlauncher 2.3.1 for riivolution. I got all exited because now I can put in dragonball z characters. After a will, hardly a day, I then put frieza over fox and got the beep of death when I wanted to choose him and start. This happened before so ill just delete it like last time, nope, whole filesystem corrupt, i cant even access the character select! Any ideas on how to stay away from this?
