Can Barely see the other players

My brother pasted hacked opengl32 file over my pre-existing one, in my half life folder…and i deleted it. Now i can barely see the other players…ct or t…and they are nearly impossible to see in front of, or in shadows… Its not brightness, gamma, or moniter settings…i tried reinstalling cs completely, and reinstalling my gfx drivers. But nothing works…graphics for everything else are just fine!!! And everything else in CS is FINE…but why are the skins…darker then normal…why can barely see them now!!!..and how do i fix it…someone please email me the answer at
