Well then your screwed. (don't take my word, just from experience... the game costed me 30 dollars) hopefully you get were i was going with that.
This is borderline spam considering the answer to this very problem is a) posted all over the forums and b) posted in your other thread. As for Nathan above, why he bought the game twice instead of just using latest order or contacting support...
Can we please put a link to this page on the header in big bold font? Something like "Bought the game and registered your premium forum account? Click here to download!"? http://www.beamng.com/service/latestorder
