When I bought & installed Gmod and then did so with CSS and HL2 ep2, there were a few quirks: For example, the options and save menus were bugged up, making it impossible to, say, turn on the ingame console. Survivable, though.
Then I tried to install my own NPCs or even spawn some of the built-in ones… I got big errors.
As it turns out, my Gmod was the folders “Sound” and “Models” I tried re-creating them and then putting stuff in them, but that did not work.
What should I do? This is really irritating me, and numerous re-installs have not solved anything!
I am using a mac, and I did NOT pirate these programs.
