Nano iPod software MIA

I bought a Nano iPod last year. My work laptop got upgraded from Win2000 to WinXP, so everything got wiped off. I've re-installed everything except for my iPod software, because it's nowhere to be found in my bedroom or at my work desk. There aren't many hiding spots, so I'm going nuts trying to find it. I found the CD for my Mini iPod, but that didn't work. I borrowed my dad's CD for the regular iPod, but that didn't work either. I asked my friend since she has a Nano iPod too, but she doesn't know where her CD is either. I checked Apple.com and downloaded something, but it didn't work. In general, my laptop can't recognize my Nano iPod (unrecognized USB device). I suppose my last resort is to call Apple, but they will probably charge me up the wazoo. Perhaps my coworker will let me borrow his daughter's CD. It's not a big deal per se, but listening to the same few songs can be a drag.
