160 gb iPod classic not showing up in my computer or itunes
I just got a 160 gb ipod classic. I'm very familiar with itunes and ipods, as this is my second one due to a burglary. I'm running Windows Vista, and when I plug in my ipod, it says the drivers are installed correctly and when I look in the device manager, nothing seems to be out of the ordinary. But nothing shows up in my computer and itunes won't run until i unplug the ipod or unless it was open previous to plugging in the ipod. The ipod screen shows the connected screen but I get no response on my computer. I've tried resetting the ipod, trying in disk mode, reinstalling itunes, and restarting my computer. Nothing works. Weird thing is, I use the same cord on my sister's computer and everything works. She's running Windows 7. The thing I really don't understand is that everything with my previous ipod worked on my computer before. HELP!
