Please some help for cod4

Hello guys, i have recently installed cod4, and i have problems with punkbuster
i have installed pb following tutorials, but when i try to get a pb_screenshot i dont see any images on the main pb folder,
that-s why sometimes i get kicked from servers,
can someone send me the pb folder with the pb screnshot and everything?
thanks a lot

for ss in co4 press  prtSc end open paint for new image
