Thanks for the tip. I was using the Shelby Cobra S/C which isn't a mod.I think it has to do with the car you are driving. I have the same issue with some mod cars which don´t work for me. If it has to do with the track I don´t know.
I've been trying to load it in race mode. So the track doesn't work in race mode? I thought the creator had said it works with a few (not many) cars.There's also no AI line, so make sure you're in practice mode and not one of the game modes that requires one.
Can you make the bit where the pitboxes are into a pitlane.it´s done. Absolut no collide at the moment.
