Our Mantis bugtracker is the best place for something like this (I believe a link towards that is in my sig)
For the crash itself, can you describe the crash itself? Did you get an "unhandled errors" message in the top-right message log in the game? Did the app close and show you some kind of "this application has crashed" message in a system popup box? Did your computer just shut down or blue-screen or something like that?
Thanks
Oh, and congratulations on getting it to crash, that usually takes effort with AIW
