I have been using my m240 for about 2 years now. I make playlists from my stored songs on my computer. For the first 2 years as soon as I clicked on the sync tab I could delete files. I would add also on WMP from Library. Now suddenly the sync tab is pressed and I don’t have music headings to edit. I have “CONFIG AUDIBLE RECORD” with no sub-headings. Does anyone know what the problem could be? I don’t know if I have to update Media Player or something, but I am confused because I haven’t changed anything on my system.
