ok thats wierd it was directly from Humble Bundle so i would think it would work... i am very sorry about this!
i dont know what i can do, since i didnt expect this, i can maybe talk to humble bundle but i am not sure if i could get another key right now...
it might take a bit, since they got no keys anymore for this game!

i will tell you the key on steam if thats ok with you? once i get one form humble bundle again

just a small reminder i havent forgotten about you but humble bundle still got no keys yet! sorry for the delay!

i got a key from another shop, i had no patience anymore to wait for humble bundle and i want to you to enjoy the game already^^
i added you in steam i will send you the key when you accept me!
