ok... I lied. I didn't stop worrying about this after all.
I'm not even going to pretend I understand how in the world I got iTunes and my iPod to work together again, but I'll tell you what I did:
So, after forcibly shutting down my laptop, I put my iPod in Disk Mode, (
http://support.apple.com/kb/HT1363?viewlocale=en_US). I was originally seeking to restore my iPod, but I couldn't do that unless iTunes could see my iPod. Anyway, after setting the iPod to Disk Mode, I restarted my laptop into safe mode. Once Windows loaded up, I plugged in my iPod, (as I'd done a few times before), and Windows recognized it, as always. I opened iTunes, which protested that the iPod software didn't seem to be working correctly, so it asked me if I wanted iTunes to repair it for me. I accepted, only to get an error message stating that iTunes couldn't fix the problem and that I'd have to re-install iTunes altogether, (nothing new here).
I decided to check my preferences, to see if it might still allow me to restore my iPod or at least to see if there was something there I could change to make things work again. Now, here is where I can't vouch that this will work for everyone, but give it a shot, at your own risk, (it's not as bad as it sounds, I think). I chose to disable the "Look for iPhone & iPod touch Remotes" under the "Advanced" tab, which I'm sure shouldn't matter, but I did it anyway, and I also enabled "Disable automatic syncing for all iPhones and iPods" under the Syncing tab.
I restarted my PC, with the iPod still plugged in to the USB port, and after Vista loaded, iTunes popped up, all on its own, with my iPod showing up!!! So... I'm not sure if my iPod is still in Disk Mode or not, but I'm going to attempt a few things, (music transfers to my iPod, disconnecting it, re-connecting it, etc...), and report any issues that come up.
Be right back.
