I can't play any maps in single player because the game doesn't launch them in the single player menu, I selected the map I wanted to play and kept on clicking the play button but it never takes me into the the game, I'm just stuck in the Chapter Selection menu :l

Nest campaign should be in place between "Biogen Corp" and "Area9800" when you create a game. Can you post a screenshots of your Greate Game menu with missing Nest campaign?
