I am also suffering from "Your account has no game accounts that can be used in this region." issue. I have the SCII-1 and SCII-2 to pick from but neither one works. My account management screen only shows a beta account not the separate SCII-1 and SCII-2 that some screenshots have shown me. I received my beta key from pre-ordering with Amazon.com. I would have bought digital direct through blizzard but I had a gift card. I hope this is being worked on I would really like to play the beta. The sticky is full or I would have posted this there.
