A problem with my material tool

I’ve recently noticed when playing that I’m missing most of the textures I had not so long ago. Has anyone had this problem before? If so, is there a way to fix it?

  1. addons installed
  2. Source games installed
    (and could you post a link to Steam Profile)

Simple Prop Protection
sfx
rp_apocalypse
Phenoix-Storms
luapad
gm_atomic
gm_apocalypse
Evocity_v2 Stuff
Combine Mech

TF2, Counter Stike, Day of defeat, HL2 and all episodes, L4D2, Alien Swarm, and Portal.

  1. I’ll bother to link it to my profile.

Try renaming your garrysmod folder to garrysmodold or something like that then start up Garry’s Mod to see if that fixes the problem.

Nope, still missing a lot of stuff.

Have you played each game at least once?

Yes.
