Weird problem. I have 2 computers. One is an iMac and the other is a Dell Inspiron running Vista. .I have always used my iPod Touch with the Vista machine and there were no isues. Now since i upgraded to SP1 for Vista when i try to sync my iPod with iTunes I get a pop up that tell me that my iPod cannot be used and to try and remove and reinstall iTunes, which I have done several times, all to no avail... Anyone else have this problem or an idea how to fix it??
