Do what I did, and e-mail sales@stardock.com with a refund request. There was another thread about it, with Frogboy giving out refund information.
To all the people saying that one should give the game a chance - I will, in a couple of months, when it's been patched up and the price has dropped somewhat; but there's no way in hell anyone should pay $50 for a beta product (which is still bug-ridden after 1.05).
The guy who made the thread knows how to do it. He made a thread yesterday about it and was told the same thing. He made another one today. He just thinks he's clever. 
Hopefully in a couple of months the game will be in a shape you feel warrants your money
