Every time I start Diablo III my server gets reset to Europe. No matter how many times I change the option before logging in to America, the next time I start the game it says Europe under where you type your username and password.
If I go back to the options, The America server is still selected... very strange. Click accept and it'll change it on the login screen too.

My client is the enGB client because that's what the retail box gave me here in New Zealand.. why I do not know. Blizzard says the servers for Australia and New Zealand are the America servers. So why do we get enGB?!

Anyways, is there anyway to make it stay on the America server WITHOUT downloading the enUS client?
