Episode 1 unstable on Windows 7 and OS X 10.8

Going back to play through TWD, and the game is pretty unstable. I tried on both a Windows 7 install and an OS X 10.8.2 install on my iMac.

Doesn't seem to be a consistent point that episode 1 crashes, but using the pause menu seems to hasten the crash significantly.

Here is a crash log from today:

Anything else I can provide?
