I had just purchased the game last night and played through episode 1. I started up the game tonight for episode 2 but the game kept constantly crashing after the "Click anywhere to continue screen" and loading for a bit. I re installed the game but it didn't solve it. I verified the files on steam and attempted to run as administrator. I am running it on Windows 7 and I do not have a controller plugged in.
Here is the file from the support tool that I read about: http://www.sendspace.com/file/8nwtal
