Hi - thanks for your reply - I tried with WMA format but then used Jodix converter and converted the files to MP3 but the problems started when I tried using windows media 11 to sync with the player?

The way I have got round it is by opening the player and then just copying and transferrring the music onto the player - this seems to have worked, so I am not sure if it was a DRM or a problem with WMP11?
