Won a region lock key

So , I won a "Orcs must die" give away about 1 hour ago and the creator sent me the key, the problem is that the key is region lock (http://puu.sh/2RQ3G.png here's the proof) and the creator does not answer to my mail
What should I do?? Am I "screwed" right??

BIG EDIT:
the user answered me . He 's a jerk , so I'm gonna report him
