Disklavier

My model is DKC100XG

Not sure I understand formatting the disk differently.  Assumed that 
a disk formatted under DOS would be all I needed.

For example, downloaded a zip file from DUG files "Dereck Barnes 
Gospel for Disklavier"   The note on the file says just unzip and 
enjoy.  I unzipped and the disklavier says "cannot execute".  

Do not have advanced owners manual, will contact my dealer.
