It told me to restart the computer for it to work so i did. Now everytime i try to open iTunes it is saying i need to restart the computer, so it is never opening up!
having similar problems, mine updated today when I plug in dock cable nothing happens at all, so that no sync connection happens, uninstalled itunes and re installed it to no joy
I just restarted mine and it's looking and acting very strangely, let you know if it goes wrong.. You can post this on the Apple forum, it's probably already on there..
