I am trying to redeem some gift cards on my wife's PC. When We click the redeem button we get an error "We could not complete your iTunes Store request. An unknown error occurred (-1202)." This PC is running Windows XP Service Pack 2 with iTunes 10.1.1. I have checked the hosts file and Windows Firewall. I can get everywhere else in the iTunes store. Additionally, I can redeem gift cards on my MacBook Pro which is on the same network. Someone please help, she is killing me.
