I recently did the iOS 5.1 update for my Verizon Iphone 4 and downloaded itunes 10.6 for windows vista on my laptop. However, after restarting like I was asked once the itunes update was complete I can't get Itunes to launch. I have tried EVERYTHING from changing settings firewalls, etc to uninstalling everything and re installing and still get the same problem. I have been searching on forums for days! much appreciate the help!
