I had 3 winners who had set their Steam profile to private. I contacted all three (you included) immediately. Two resolved the issue I had with them (not being able to check them with sgtools) within 12 hours after the giveaway was closed.

You decided to wait until now. I opened a support ticket extra for you asking to check your profile on my behalf. Unsurprisingly no answer until now. Life could be so easy if you just set your Steam profile to public for a few minutes and the key is yours :)
