Unspecified Problems

hmm, after a bit of experimenting i have figured out that it is indeed not that it won't do certain battles, it just won't do siege battles.

any battle where the city is involved on the battle map my game closes down on me. Why would this happen?

I'm no expert on MTWII errors, but if I had to guess I'd say you might have some corrupt files specific to the buildings. Can you try a siege against a fort?

Anyway, my advice is reinstall. That's a good general first line policy for generic errors like this one, as it's going to be very difficult to narrow down.
