Some issues with L4D2 models

Recently I have been wanting to make a L4D2 machinima using Gmod, and one of the things I needed of course are the zombies. So, I go into the L4D2 folder in the browse tab, go into the “Infected” folder, and then I scroll down to see what is at the bottom of the folder, and the game crashes. Another thing I have problems with is whenever I do spawn one of the ragdolls, they look like they are covered in various colors of paint.

L4D2 models have been messed up for a while now. No idea why you’re crashing however.
