I've just bought the retail DVD version of the game a few weeks ago, and was going to try it out tonight. After installing and starting up on episode 1, I can basically do everything all right up to the point when I started using my keyboard, then the game froze on me. The music kept playing but the screen is frozen. The only way to get out of there is by a hard restart of the computer (can't force-stop the program in program manager either). It didn't matter which key I hit on the keyboard. I tried ESC, hoping to save, but frozen; tried ASDW to navigate Max, frozen again... Is there anyway around this?
