I just got a new ITOUCH and when i try to sync with my laptop (WINDOWS VISTA) this error message comes up "This iPod cannot be used because the required software is not installed. Run the iTunes installer to remove iTunes, then install iTunes again." I have uninstalled and installed itunes about 10 times now. And still can't sync. It is recognized in my computer as a portable device but itunes does can not connect to it. It works on my desktop with Windows XP. Please help me out. THANKS.
