File not found error!!! help me

I have an MPC 1000 that I have had for a few years and now when I try to load programs from my CF card sometimes it will stop in the middle of loading, say "File not found" and will totally stop. Sometimes I can take out my card, put it back in, and do this a few more times to make it work. I downloaded the JJ OS for it and it did not fix this problem. Does anyone know how to fix this?

Tryed another cf card?
Another option is to format the card (after u've backed up ur ish) and try again

YEAH IT SOUNDS LIKE YOUR FLASH CARD--TRY LOADING EACH PART OF YOUR SONG AT 1 BY 1.THEN RESAVE OON A DIFFERENT FLASHCARD..SOMETIMES MY CARDS SCREW UP TOO---DONT KNOW WHY!

Don´t forget reformatting your new cf card with the JJ OS before you put any files on it.

Thanks for all the input homies... The CF card is formatted to the new JJ OS and maybe its the card itself I might try a new CF card but this has been happening for a while and I thought the JJ OS would solve this bug. Maybe its time into turn in the 6 year old mpc. Ive been debating trading it in and getting a MPC 2500. Any comments?

P.s. the production on the new T-Pain is sick

If you dont need the extra outs, the 2500 is a waste of money imo.

Thinking back I bought the MPC 1000 pretty much right when it came out... could my problem be the actual mpc? If i need to buy a new MPC i will I just REALLY need to get back to the studio with it
