So..you put them in the correct folders and everything? I'd also trust you know which main folder to put your skins in. For some people, it valve, but from me, it's steam.
And please use proper grammar also, we value that around here. That includes not using all caps.
So do you extracted to there? You may have to do what I do, and manually do it. I look at the folder, materials, then models, weapons, V_models. I then move my model from my folder, to that location. It's like following a trail of candy.
