I suggest you go to your ..\N3V\TS12\bin folder and run TrainzDiag.exe. If any failures there, fix them first. Especially OpenGL which I beleive is required for CM to run.
The TrainzDiag result should tell you what graphics card you have - you will then need to visit the website of the graphics card manufacturer to download the latest version of it's drivers. If you are unsure, post the name of your graphics card.
Actually I'm good. I figured out that my driver was 47 months out of date. Thank you guys so much! If I didn't pay attention to the Trainz Diag, I would've never fixed this!
