OS problem?

Im not to sure what exactly I did, cause I was stoned and on auto-pilot when I did it, but I'm pretty sure I screwed up my OS of my mpc2000xl. I was on the save/load screen and before I knew it I had soft keyed my way thru the "no turning back, are you sure you want to do this" screens. Since then my Mpc wont recognize the snd. or prg. files on my zip disk, the seq. & .all files are there but there of no use w/o the samples. I've tried installing the lastest OS and it dosn't help any. I don't have my Mpc right here now so I can't give a perfect account of whats wrong, but I'll write it down and post the symptoms. If anyone know what I might have done, I'm all ears.

I think we are gonna need a little more info, so please post as soon as possible........It sounds as if you wipe the disk, but if you can still see the files on the disk then I dont know. But I am more than sure we can get you going again
