Hi Aud,
I had that same problem when I down loaded Vol3. When I took it to the kn6000 it showed a mix of songs and style entirely different to the Vol 3 list. When I put the floppy in the pc it listed all the songs on the list so I cleared(formatted) the disk, downloaded the file again and this time I got all the listed songs onto the keyboard.

One of the peculiarities of the pc I guess.
