Just Cause 2 Crash

[Pash91]

Hello,
I've been having seemingly random crashes that I THINK I narrowed down.

I am playing on all the lowest settings possible. The game was working great for a while I started the racing mission in Panau city (where you have to drive on the highway for 25 checkpoints; it's a 1 star mission). The minute I get off the offramp and turn left, my game crashes. It's incredibly frustrating as I'm stuck doing this mission and can't go anywhere else. I noticed that the timing doesn't matter. I have fully updated drivers on Win 7.

Any help would be greatly appreciated.
