Orion Astronaut

I downloaded the DMP client and followed the steps with the installation, but all I get when I start up the game is window saying DarkMultiplayer-Disclaimer. Is this supposed to happen? If so, how do you open it (I have tried clicking it, trust me)? Am I missing something? I really want to play this, and I have been searching for hours. Does some one now anything? Please Respond!

I love it! Probably the best stock Dream Chaser replica out there!
