thanks for reporting
is it a crash to desktop too or do you get an windows error dialog right afterwards?
do you remember which race you played and which other races where involved? what map have you played on? instant action or multiplayer?
It's usually a crash to desktop and then it wants to send an error report to Microsoft, It does this as all of the races for some reason, and I always play with seven computer players or six computer players and my sister, so both Instant Action and Multiplayer. I usually play the Tic Tac Toe map, but it does it on others as well.
Hope this helps.
