has this happened to anyone else?

iight so check it.
i bought some sounds for my shit and theyve been working fine untill now, but yesterday whenever i transfer my shit from pc to mpc (no program creator program) ill go to load them and instead of my shit its just some staticy bullshit, each sample sounding the exact same, but maybe one will work.
has anyone had this happen before?
if so you think that shits fixable?

it could be that the samples aren't set to the correct format or frequency.
The need to be uncompressed 44.1 khz, wav files to play back on yer mpc 1000. hope that helps.
