Code Issues

[Mister..C]

Im on CFW 4.01 M33-2 and using Nitepr Rev-K Stable. All of my codes are from the no ban/error database. They were working earlier today but now every time i select my codes exit nitepr and hit the note the game freezes and my psp turns off. Anybody have an idea whats going on. I already deleted and reinstalled nitepr. Any suggestions would be much appreciated.

Thanks a bunch,
Mister..C
