Please install 'SmartException' from the free stuff section in Stardock Central. Make sure that SE is running and start your game as normal. If the game crashes it will generate an exception report that can be emailed to firstname.lastname@example.org.
Include in/attached to the email:
+ A description of what you were doing at the time.
+ How to reproduce the crash (if possible).
+ A zipped save (if applicable).
+ The appropriate debug.err file.
The devs cannot help if you do not provide these details!
