I reinstalled my windows, and I reinstalled everything, all my content and my addons, and everything works swimmingly, except for one aspect.
NOTHING from HL2 works. Every vanilla prop, every HL2 Model/Texture/Sound/Entity are errors, and I cant see my physgun nor gravgun.
With that said, I have EVERY source game mounted, and the content is properly installed and working.
Any help or ideas of what might be wrong?
