FM13 skin installation

I downloaded a skin from a different website and am unable to find it in the game. I've placed the folder in Documents/ Sports Interactive/ Football Manager 2013/ skins location, as well as untucking the skin cache and reloading the skin. Even after this I'm unable to see the skin in the drop-down menu.

What am I doing wrong?

Documents/ Sports Interactive/ Football Manager 2013/ skins/put in here yeah?

Have you unrar.d it?

Is it for the game mode you're playing? FMC skins don't work in FM and vice versa
