Save files corrupted and unable to save

[GoogleCodeExporter]

I tried using a CTF theme, and when I did, I was unable to run any isos. It 
wouldn't let me change back to normal, so I tried changing ISO drivers, and 
when that didn't work, I connected my PSP to my PC and changed the game.txt, 
pops.txt, etc to have cxmb 0. I turned it back on and ran CFW again, and it 
allowed me to run the ISO I wanted. But all my saves were corrupted and I was 
unable to make a new save.

How can I fix this?

Backup the content of your MS on your PC then format the MS (System settings> 
Format Memory Stick).
After formatting your MS copy only the /PSP/SAVEDATA/ folder back yo your MS.
cxmb plugin is meant to be put in vsh.txt ONLY.
