EB,
be warned...the iPod only synchs from PC to iPod, never the other way.
So if you install the windows version, and then try to synch with the PC, it will wipe all the data from your iPod.
However, if you have moved all your music to the PC, then reinstalling the iPod software from your PC, alowing the iPod software installer to reformat the iPod, then re-synch with iTunes will sort everything out.
Don't want you losing all that Maiden stuff
