MX Simulator

I just bought the game today after seeing it so many times on youtube ive wanted to give it a go finally. When I downloaded new bikes and tracks nothing worked. I have run them through and gotten the files I need, but tracks show up white and bike mods dont even show up. Any way to fix this stuff?

Update: Only thing that wont work is the bikes.

Check under the KTM or Husky graphics. People like to use those instead of the correct bike because of the preferable dyno numbers.
