Purple and black dots :]

[Elmo]

Well, I joined the Fearless RP server and there was new models and textures, My computer downloaded them and when I joined I saw Purple and black spots on all the roads and most of the walls, I also can't see certain signs
(As I hit one in a car and assumed it was a sign)
And I also can't see the Mafia Boss
Please help me Thanks

It's your gmod. We have had this posted before. Try reinstalling hl2 and css, also gmod. Check to see if they are mounted on gmod.
