Um, so I ordered a copy of the collector's edition for NA. But when I received the game (finally getting around to installing) it came with an EU registration code? It doesn't work for NA registered account. Is there anyway to resolve this, or swap for a new code?

I tried putting in a ticket, but it's been ignored for 4 days now, and I obviously can't return the game. I feel rather cheated having paid $80 for a game I can't even register.
