Cannot connect to the iTune Store from within iTunes.
Can not connect to the iTunes Store from within the iTunes program on my PC. Using iTunes 10.4 on a XP Sp3 system. Everything worked fine until a few days ago. Now the iTunes Store (Store) will not open. Tried rollback, disabling firewall, anti-virus etc. Not working. iTUnes Diagnostic says I can connect to the net but the screen remains blank, except "No connection to firmware update server" is listed in the Diagnostic.
