RP_Christmastown error

I just recently got RP_Christmastown from here

And when i installed it, a bunch of it is white lines, a black-and-pink checkered pattern, and red error signs.
What do i do to fix it?

Means you dont have the textures and the errors are props that you dont have.

How do i get the textures and props then?

You probaly need css.

Counter-Strike: Source?

Yup… There’s a 75% off deal for it right now on steam so might as well buy it now.
