UPDATE 12-12-2012: Downgraded to XNA 3.5 Again
After a short discussion we have decided to skip XNA 4 completely and keep running on XNA 3.5. This means that those who got the error message "No Suitable Graphics Card Found" should now be able to play the game. The achievement should also be fixed so that its granted as soon as you start an arcade game IF you've gathered 40K gold since the "Not a War hammer" achievement was released to the public.
We apologies for the problems our recent update caused and our goal is that everyone who have trouble with our game should be able to get in and have some fun :) Please post on the forum if you keep having problems with our game.
