Data corrupted or something?

Alright i finally got past my other problem, but i have another problem now. Whenever i play some models are just big red “errors” and most of them arent there at all. The guns arnt there either. PLease help i wanna play this so bad, ill give a link of a screenshots of what happens:

Trying running and playing Half Life 2.

I have already ran but i gues ill try again.

Edit:Tried it and it didn’t work.(and btw i ahvnt ran it while gmod was installed yet)
If anyone knows how to fix this please let me know.

Edit edit: I solved this by dumping the gmod folder(again)
