Eye Texture Problem

OK, so today I was playing Gmod and I decided to make a machinima, but for some reason, the ragdolls eyes are missing, they are the purple black checked missing texture thing. This does not happen on the default half life 2 models but it happens on custom models, such as:
Miranda - Mass Effect 2
Half Deads personal Skin
Rebecca Chambers
Enhanced citizens.
Everything else works apart from some railings in EvoCity, but I think that it was a bad download.
Any help will be appreciated. Thanks

Btw - I have tried to download new eye textures but that seems to do fuck all.

I had the same problem… 8/ this is a old post but still any help?

No.
