I bought a digital copy of Diablo III for the Americas Region...however when I login to the Americas I get Error 12. But when I switch it to Europe I can log in. I don't want to play on the Europe servers. How can I switch this around?

And yes, it says on my battle net that I bought the copy in the Americas and when I switch it to Europe there is no transaction history.
