how do i (heck, CAN i?) sync my Creative Zen or Zen Micro player with
iTunes 6 for PC?  I am having trouble importing my music into the
Creative Media Organizer and I am hoping that I can just keep using
iTunes, but sync up with my new player(s).

thanks for any help you can provide!

PC iTunes does not fully support non-Apple mp3 players.  However, it
seems that the following page may help:

I'm unaware if the Creative line supports aac, but I highly doubt it
does.  Also, if the creative software is not functioning correctly,
contact Creative.  They should be able to help you.  If all else
fails, I believe you can treat your mp3 players as hard disks and just
drag and drop from your music directory to your device.

Have you tried downloading the music in something else than itunes?
Like Limewire or Zultrax and simply having them on you computer?
