Overland game crash w/ AI

[Spud]

Hi Guys,

Has anyone had problems w/ Campaign Overland not responding when playing against AI.

Am currently 73 turns into Mine Run Campaign and each time I hit next turn button for AI to make its moves my screen turns opaque white and a message flases up saying "cpd.exe not responding."

I have started some other Overland scenerios to see if the problem can be repeated, by so far no such issue has arisen.

Am using Windows 7 and I have plenty of RAM and a huge space on harddrive memory. My computer is also virus free.

Any ideas?

Here's a zip of the battle.btl if anyone wants to take a look.
