Yes, there is.
I would still recommend you try to make to iTunes work, though - if it's version 7.0, be warned, it's very buggy. Did your iTunes work before the upgrade? If so, maybe download and install an earlier version (I don't dare install 7.0 : )
Failing which, try another app.
The most commonly-recommended one is called Anapod Explorer, which offers iPod management through full Windows Explorer integration under My Computer, easy drag and drop iPod transfer and iPod backup, PDA function support, photo and video transfer.
Anapod supports all iPod models available in the market, and all storage capacities. It's also compatible with all iPod firmware versions.
The computer you're transferring from or to must be running on Windows 98SE, ME, 2000, or XP - you are fine, in other words.
