CSM Trouble

Hello, I am trying to start the Can-am mod in csm, but the cars do not show up when I start the mod through csm and any mod for that matter. It took awhile to get CSM to work in the first place, but I got it going. Except now I can't race any of the cars? I would really appreciate any help into this, also I would also like to give a big thank-you to all of the modders out there for creating some really great sets and cars.
