So I've tried to copy music to my Creative Zen several times, but after all of my music is copied into the media library, it does not show up on the actual player. It seems to be copying the music fully, and my Zen will update itself after unmounting it, but when the music does not even show up.

I thought it was a problem with my mp3 player, but it works fine with other computers. Complete linux newbie here, so I could use a bit of help, heh.
