Consitent crashing to desktop

[vanzagar]

I have a save game where when I hit next turn, the computer AI attacks one of my castles, after the castle defences have fired the game crashed to the desktop. It has done this 5 time in a row now, is there anywhere I should send this save game file, or describe it to someone, or do the developers generally not really care...

I have tried it on my main computer and my laptop, both with the same ffect. Laptop is about a year old will all latest drivers, main computer is:

Try driveragent.com/scan and see if there's something you need to update.
Next, shut down all unnecesary programs (attach a dxdiag or hijackthis file).
Can also use Wintasks 5 to see all running processes.

After that is running at stock speed even if other games handle overclocked hardware just fine.
