Answer 1

Same problem. I can see the itunes store so not a problem with windows firewall. The account is active on my iphone so i know i am not locked out. I can connect the PC to my iphone so i know itunes is working ok. It is just logging into itunes on this pc which doesn't work. Only thing I can think of is that the email address I use for my apple id has been offline for a while and is working again now, I'm wondering whether this has been the case for others who are having this issue?
