Well that's really something. The first key I had bought a long time ago from G2A, and decided to give away in this. When you said that one didn't work, I know that's always a possibility with places like G2A. So, I went and bought another key today, but that one doesn't work as well. If that's the case, then I don't think I can get this game for you because it's no longer on the Steam Store. This is unfortunate, but I tried. The other two people who won were able to activate their keys. Pretty unlucky that two keys I sent you are both duplicates, when I spent money for both of them through a supposedly reputable site. Sorry.
