A small group of us are currently playing on EU 1 by the way guys, appears there is a fix to this problem.
When the game requests your CD key; enter your CD key for native, not for NW. You can find this in your steam library by right clicking on Mount and Blade: Warband and clicking on View CD Key. Hope this helps. Spread the word!
p.s. Sorry to those of you who were just about to go and meet some women, change of plans I guess.
