If you had the Diablo III beta installed, you might come across error 33 &#8220;battle.net is down for maintenance&#8221; while trying to log in. This is because there is an old registry setting pointing at the US rather than EU login server.

Take a look in HKEY\_CURRENT\_USER\Software\Blizzard Entertainment\Battle.net\D3.

I solved this by deleting the entire &#8216;Blizzard Entertainment&#8217; key. From orbit, just to be sure. Works like a charm.
