Well in some maps some items and walls apear pink

to get rid of it they told me i have to download some textures
but i wasn't able to find any

Can some1 tell me where can i find textures for CSS?

I think its your graphic card. Mayb it doesnt support. Or try updating your driver.

The black/pink squares are there because of missing map textures.

I dont know where to get them, sorry.

Perhaps you could try downloading the maps again?
