Wrong file!!

I just updated my MPC2000XL to a Flash drive loaded with a 1 gig card.

The problem I am having is that after saving my sounds an sequences to it,
(from my mpc memory) when I try to load anything from the card I get a "wrong file format" for sounds or "wrong file!!" for seq and songs.

Could anyone point out what I am doing wrong?
Thanks

I did not mention it but I did format the flash disk before saving on to it.
My sounds and sequences were previously loaded onto an external Zip drive and that's what I use to load my MPC2000xl memory.

Again, any advice would be much appreciated.

anyone?

Is this happening with everything you save to the card? Maybe try saving your sounds as wavs and see if that makes any difference...
