I have a 30gb video ipod. For just over a week, my ipod doesn't connect to iTunes...usually when i plug my ipod into the computer it will come up with my ipod name and stuff, then when i tried it again it didn't show up in iTunes. So i couldn't put any songs on there.

Even though it wasn't showing up in iTunes, it had definately connected to the computer and it was also charging.

But now it doesn't even charge at all, and it doesn't even connect to the computer...

what should i do??
