With help from Valve we were able to resolve all the problems we were having with the distribution system. The game is now fully playable through the steam client. The no executable problem and the reinstall problem we were having as a result of not have the game configured correctly are fixed. If anyone was having a problem launching the game or was frustrated by having to reinstall the game each time it was launched we apologize and have fixed the issues. Now you can hop into a Rhino or Bayonet, build a base, and defend it from the enemy whenever you want!
