TWD: Game is broken

Just bought this game recently on steam sale and I'm having quite a few problem.

Having a controller turned on crashes the game to desktop. Disabling it gets the game to launch, but the controller doesn't work if I turn it on during game.

I played about 2 hours with keyboard and mouse and took a break. I came back and my save doesn't work. It starts me at the beginning of the game again.

The settings like display options, etc all reset when exiting the game and relaunching.

OS: Windows 8 x64

PS: This gameplay/story is freakin' amazing of what I've played.
