Ugh, I just installed the game today, tried it for 3 minutes. Everything was running fine. I then decided to quit, opt into Steam's beta to enable game mode, plugged in my DS3 (using MotioninJoy drivers), plugged in my HDMI to play on TV, but whenever I tried to launch the game... nothing.
I reverted all the steps mentioned above to the old ways/settings, and still nothing. I reinstalled the game, nothing. I reinstalled Steam, nothing. I googled and tried to reinstall my DivX and run it in compatibility mode, but still nothing happens when I try to run.
The loading circling cursor appears for a few seconds but that's about it. The task manager shows "The walking dead - Steam" under Steam for a few seconds, but then it disappears.
I'm playing on my Asus G73JH, Win 8, AMD HD 5870, running latest stable drivers. Again, the game was running fine until I decided to move to the couch. Fuck the couch, I say!
