there was an error with paypal and humble bundle guys were so nice to give me another copy while i was waiting (it actually took more than a day before i recieved my actual copy)
finaly i got a copy, i have no use for, so i'll give it away here.
sorry, it's not a gift code, it's an actual HIB3 key, but i haven't touched the codes from it, so you will be able to activate it on steam.
