Windows crash report after closing

I'm fiddling with the car tutorial from the asset store. So I managed to get the car on the track and such... but the problem is that 10 seconds after after playing(closing the .exe file) an error pops out stating that the .exe "stopped working". The reports show an access violation. This does not happen if the .exe is closed from the "Configuration" dialog(the one where you choose screen resolution, input keys, etc). This happens on Windows 7(tested on several machines). Can someone suggest what's wrong. Thanks in advance.
