L4D Model fix REQUEST!

Hi, I followed a tutorial on FPSB on how to import L4d models into GMod. I got the models in, but the Survivors have the messed up textures (the checkerboard, of course.) in their eyes. If i look at them close, I can see their regular eyes. Can somebody say something? Tell me what to do.

EDIT: The textures are good when i play l4d. so its not my graphics card.
