Problems saving my programs on Mpc 2500 w/harddisk

Im trying to create a brand new program right now under a name ive never used before and the mpc keeps saying file exists.

I really need help on this issue.

By the way Im saving it to my hard-drive on the mpc 2500, Ive lost a bunch of samples trying to get this straight and its beyond my knowledge as to know why this happenening.

I also cant save a new folder because everytime I try it says the same thing. Is it the lack of memory on my my mpc?

Thanks
