Model spawning with bright pink texture?

[ThatBenderGuy]

Ok so I downloaded a model and because of the new way GMod does addons I have to do it all manually. Placing the corresponding folders in the "models" folder, "materials" folder etc.. as well as editing a spawnlist so I can spawn it in game. The only problem is when I spawn it in game it comes in bright pink. Which is odd because if I edit its icon it has the texture. In game it does not, any solution?

Here's pictures (Yes I know it's a +18 model)
