First of all, I'm having a blast with this sim, lots of fun. I've installed maybe 10-15 tracks and its easy, just drop the unzipped track into locations and it works right away. That is except for a few like Bathurst and Autopolis. I unzipped them and did the same as the others tracks, yet for some reason they don't work. The loading bar goes for a little bit then just stops. At that point the game freezes and I have to shut the program off. I really want to see Bathurst, especially after I heard its such a great reproduction of the track. So whats different about these tracks that the usual procedure doesn't work?
