How come my other maps in Counter Strike Source have checkered violet texture?

How come my other maps in Counter Strike Source have checkered violet texture? Other maps are fine but others become so unplayable because the map is violet. How am I going to fix this problem?





Thank you very much in advance.

because you don't have the 2d texture file that the map is using. If you don't have the 2d texture file, the texture will show up as the purple checked texture.
