i just got this MP3/4 player for my birthday.

i've read all the manuals and stuff but can't get it to work with windows media player 11 playlists. i sync the device and drag the playlists to the right pane. they sync to the device. BUT the playlist track listing itself DOES NOT transfer to the player.
i've tried transferring the .wpl (playlist) files to the player using drag and drop into it's playlist folder, but it say's the file format is not supported!

please help, i'm so frustrated with this. i previously had an older philips MP3 player that recognised my playlists and everything (but my brother lost it), and i just can't understand why this player won't do the same. grrrr...
