hey everyone

i accidently formatted my mp4 player for some reason. I don't know what made me do it..i must've been hullucinating or something... and the record and voice folders deleted so now my player can't record voice anymore. I was able to replace all my mp3 files but not the folders. Is there anyway to fix this problem because i've already tried creating new folders with the same name and everything. Do i have to renew teh firmware or something? i'm not sure...
