Hi Rog, Like you, on occasions where I wish to play an MP3 file through my KN7000, I gave up on SD Jukebox with all it's necessary 'pesky' check-in - check-out stuff and incompatibility with versions of Windows. It's so much easier to just use an MP3 player attached to the Line In ports on the KN7000....
