[gm_mount² and gmod]Left 4 Dead eyes

Hello, I downloaded the gm_mount ² of this post : http://www.garrysmod.com/news/?p=9246 . I have Left 4 Dead and clicked it to pick up models Left 4 Dead but the eyes of survivors and some zombies are black and pink. My Left 4 Dead is true.

The only ones who escape this are : Boomer,witch,hunter,tank and few more but the rest is with the black eyes and pink

Sorry for bad english.

It’s just your Direct X, you just need to upgrade it.
