TOPIC:

it says dtr2.exe has stoped working how do i fix that.

Well, it could be several things. You should have an [error log] and I'm not sure where that is now. Been a while since I bothered to look. It may be in Doco's and Settings.

It could be that you have a skin that's without a chassis. You could have a Zipped folder inside Data somewhere i.e. Tracks. Check all your folders to make sure all is correct before deleting and starting reinstalling game again. Maybe it's the Render file that's not right?
