So i bought CS:S (Counter-Strike: Source) and added the content on GMOD. It worked for a couple of months then the content stopped working, by that i mean purple and Black squares and errors. I checked the extensions and it show Counter Strike but the actually props and weapons etc.. dont work. Please help me.

Did you try cleaning your registry ? Re-install Gmod and try again. Some files might have gone corrupt.
