So yea someone gave me a beta key and it does not work, I was so so happy until I tried it and it did not work 
I just want to play this game and help iron out some of the bugs so it will be an amazing game.
he probably trolled you out with an used key, that’s bad of him, toying with people like that
Or maybe he is in a country who’s not allowed to enter the beta test
You got rick rolled man.
