Emax

I am a newbie!!

I went out bougth 100 ddsd disks for my emax.

I have used to EMX prog that is posted here to make some disk sounds 
and some sounds work ok.

I am trying to do some sampling of my own. When i put the disk in to 
the emax and format is seems to go through, as i try to do anything 
else it gives me "diff software Rev"

How do I over come this ? do i have to update the software on the 
unit? and if so how do i accomplish this.

Thanks
