I just tried that, using the example tracks centerlines and rdf file, it worked and I was able to load into the game! Do you have any idea what I might have been doing wrong? If I create my own center lines and name them "Area 51 Mx_start.ctl/Area 51 Mx.ctl", am I not able to use the example tracks rdf and change the coordinates, then name it "Area 51 Mx.rdf"? I'm not sure what I was doing wrong. Thank you for the fast response! your guides have taught me a lot throughout this process!
