Request New Winner? Remove Contest?

Just wait, when support rerolls the ´not received' black mark will go away :-)

You're doing the right thing, so don't worry. I once had a giveaway where I had to re-roll three times because the first three winners were not eligible to enter the giveaway. You do, however, want to keep records of your attempts to reach the winner (copy of the email, screenshot of the Steam chat, things like that) so that you can provide evidence to Support if asked for it.

Yeah be patient and hopefully support will get back to ya, best of luck and as long as you have so data supporting that you've followed the rules nothing bad should happen :D

Thanks.
I have just had a reply from support with a request of proof of the email which I have now done.

Well, support finally did do another re-draw, so thanks to them for that. However, the new winner already owns the game as well.
I don't want another re-draw this time and have put in another support request to hopefully have it removed. If they do, I'll just stick the key in the forum or something.

Right, support have kindly removed the contest. As it was only Orion: Dino Horde, it was entirely possible that everyone chosen may have already had it.

But if any of you haven't and want a copy of it, reply something funny and pick the one that makes me laugh the most when I get back in half an hour. I'll add whoever it is on Steam and gift them the game.
