URGENT HELP ON PCG

[lucabbrasi]

Hi, I've made all my Combis, with proper programs and settings. Saved all with a SETUP.PCG file. Then I've tried (with LeLibby) to organize some other programs in my library. Re-loaded the SETUP.PCG and...voilà, all internal programs in the combis are changed! Hours of work lost!
I don't have a previous setup name, but for sure I've re-written over the same file other previous versions: is there a way to recover these versions? Thanks a lot, I'm desperate!
