When I turn on the device and go to the library, playlists, and hit "import playlist file" the playlist I have transferred shows up for import (an m3u file). I then hit that playlist, , reply yes to "import playlist file?" It says "now processing" and then "an error occurred."
The device accepts, and runs, M3u playlists from the XDAP-Link software. The instructions also say it accepts m3u, m3u8, pls, and wpl.
I have tried exporting the playlists in M3u, and M3u8. The device runs M3u files from XDAP-Link, but not from MusicBee.
