MX Simulator

Whenever I try to join a server and it going to the mx sim screen it says it can't find the track even though I have it so what should I do or what am I doing wrong.

Make sure your track isn't installed in a sub-folder. You want it directly in the "MX Simulator" folder. If you do something like put it in "MX Simulator\tracks" it won't match server's track name.
