Disklavier

For one day everything started to work perfectly again.   Then I pushed the 
play and the on button to see if I needed an update and it said I needed an 
update to 1.44.  I downloaded the update from the Yamaha site and now it won't 
play any disks except the Pianosoft. I formatted a floppy on tyhe DKV and then 
tried to copy another disk on my computor but it re-formatted before copying 
and will not play on the DKV. All the bad floppies can be read on my PC.
