hey sorry I've boiled it down to I've tried everything and it doesn't work.
but here it goes.
contacted the developers through their website 4 times over 2 weeks most recently being today. Check their forums and devlog. I check these forums, and the Steam Forums. I've tried asking for help on all forums. Checked on Desuras Forums. Checked Desuras key page many times. Tried inputting the game key as the steam key. ANYTHING. I have tried anything and everything to solve this ridiculous problem. Sorry I wrote all that stuff out on other places and just summarized it as "i tried everything" and there is no way you could have known what I meant exactly.
and it'll eventually be fixed, and we can still play the game (which is awesome and very fun)
