Diablo 3 beta Error 12, This Battle.net account does not have a Diablo III license attached to it

Diablo 3 open beta starts today and will end Sunday!!

If you get this error while log in "This Battle.net account does not have a Diablo III license attached to it. (Error 12)" you probably need to check your downloader client or your options!


Check if you have downloaded the correct client: European, or American

Then, once installed, go to "Options" in the log in page, go to "Account" tab, and check your "server region selection": you have to select "america" because this is the only place where the beta is live.

Happy beta!!
