Can't sync iPod Touch with new computer
I bought a new computer and downloaded iTunes. But it won't let me sync my iPod Touch. It says my computer is not authorized. So I click on iTunes Store and "Authorize this computer." But it still won't let me sync, it says "This computer is not authorized." So I click on "Authorize this computer," and it says "This computer is already authorized." And on, and on, and on.
It also says that I am already authorized to sync on 3 out of 5 comuters, but I only have one iTunes installed -- the other two computers have been retired.
Is there any way I can reset things and start fresh as if this is my first iTunes install?
