Playlist issue.....

I just got my 8mb fuze (love it so far).

I have transferred a bunch of music - no problems.  But, I made a playlist that has a lot of stuff on it and transferred it using WMP v11.  All of the files transferred fine but when I look at the actual playlist on the fuze, most of the entries are gone.  It had about 60 entries and on the fuze it only has 13 and they come from somewhat random places in the original playlist.  I have some other playlists that seem fine but they are not as big.

What can I do?
