This happened a couple of days ago, thought you might be interested
I'm running the game on a Packard Bell laptop having Core i3, ATI R 5470 (512MB) with 4GB RAM under Win7. The game when getting back to port simply stopped, while having the windows error message attached below.
Other than that I'm having a lot of fun in the game, and this happened only once yet.
