Bug fixing and the crash dump file - help required

[cf_nz]

I'm a relative novice when it comes to modding with the SDK. I have merged the ranged field bombardment from Dales Combat Mod with the Route Pillage mod by TheLopez.

I have however hit a snag and get a crash to desktop when a seige unit destroys a tile improvement. It seems to have occured since I added the TheLopez's Route Pillage mod.

Can people give me ideas on the ways to track down the problem, how to use the crash dump file etc. I know a little C++ but not enough to easily look through the code to find the problem.

Thanks in advance.
