Hi, recently, my cousin and I bought this game. All good, but when my cousin tries to connect to a Stop it Slender server, it starts to download the files. Nothing wrong with this, but when it reaches the addon Outland v3 his game crashes. He tried to deleting the addons and tried too to install again the Gmod but this options didn't work. Could you help us?

P.D: He tried to download this addon in the workshop but when he enters in a game, the server downloads the addon again and it crashes. BTW, his steam account is PueRCoYo.

Thanks for your help.
