JudasIscariot: Please write to Support when these kind of issues arise so we can help you better :)
ToasterMeltdown: There's no additional information to that, either way I got it working with vm with an image of Win Xp.
edit: By the way it's a great game, I've played it already for almost 20h.
It's awesome that you got it working but we'd like to hear about these kind of things so that we can get a better grip on which systems are affected. If there is a common link that we can isolate then we can work on fixing the game more and make it work better on the affected systems without having to resort to workarounds like you described in your second post :)
