Thanks, guys, for al the help.
I'm back up and running...restored my HD2 to factory condition and have everything back in place...well, most everything, I could remember...lol
I hate WMP on the desktop because if you begin a sync and then remember there was something you didn't want going onto the device, WMP is determined not to be changed. It actually is rather frustrating how WMP works.
I tried MediaMonkey and it works the best, but the playlists it syncs don't work on the HD2. I can just drag & drop files, but I was wanting to have playlists.
