I’ve uninstalled iTunes normally twice, then I did it again and deleted anything that looked like a settings folder. The store still only loads twice. I’ve changed the LAN Settings, checking and then unchecking “use a proxy server”. I set IE to default settings. I made sure Windows Firewall was letting iTunes through, by turning it off and then on again. I put netsh winsock reset into the command prompt and rebooted.
None of this has worked. Anyone have any other suggestions?
