downloaded itunes 10 couldnt connect to store, uninstalled and reinstalled but still no connection, it does try to but nothing happens. tried to reinstall an older version but it wouldnt run because, itunes library.itl was created by a newer version. someone on apple forum suggested renaming it, but i wasnt able to do that, not even in command prompt. deleted all itunes related software and folders reinstalled the last version that worked, 9.0.3 but even that wont connect to the store. someone else on apple forum said something about ping, no idea what that is. HELP!!!
