Yeah my installation is borked. It says I've got 3.68GB left and it just sits doing nothing. Closing the game down a few times eventually got me into the actual game, I setup my settings, but I couldn’t do much in the game. The tutorial screen was all greyed out, and the main flight map wouldn’t let me launch the game after setting a departure airport in a Cessna 172. There doesn’t appear to be an option for a repair of the client either. The repair in Windows just repairs the 1GB updater, not the actual game itself.
