Textures buggy on CS source

[titaniummonkey]

In CS source some of the textures are checkered purple and black. I had the same problem on HL2 and went to steam://validate/220. This fixed the problem for HL2 but not for CS source. Can anyone tell me the site for CS source?
Thanks in advance.

Go into the steamapps/accountname/

And delete the counter strike source folder.
