Tracks Why the game close to main menu when I try to enter in a track or use a car from a mod?

Hi guys! I have an odd problem. A friend of mine just game me some tracks and cars from his dlc packs. Every time I try to run the track, or car from him sesion closes to main menu. Why?

So are they mods or DLC? Two entirely different things.

If they are DLC you need to buy them.
