Plutonium

I am a little bit confused. I landed here because I wanted to fix the CZ75 Game crash bug and I do not want any camos. So what should I install and drop in what kind of folder?

Everytime when I play zombies in bo1 the game crashes. It was not alway like this. It crashes since I use the FOV Command cg_fovScale 1.5. Does anyone have same experience ?
