Make sure your computer's date is set correctly and that is accepts cookies from the ITunes Music Store
I keep getting this error. I have tried to authenticate my account so I can redeem a gift card and it keeps giving me the same login screen and then asks me if I forgot my password when I can see that I am already logged in. When I attempted to put in a different account I get the date/cookies error. Thoughts?
