G'day to ever reads this. If you are having problems with Punk Buster on ANY game do these 2 steps and it "should" work we hope. 1)- Update your PB to the game you play (PunkBuster Online Countermeasures) 2) If update doesn't help.. Find the Game Folder, E.g: Call of Duty and Search for the "pb" file, once you found it, Delete it. Then grab your Installation CD 1 (If has more than 1 cd's) Close the application that it brings up and go to My Computer..And where you see the Game CD's name, Right-Click and go to Explore, find the "pb" folder and copy & past it into your Game Directory. In most cases that helps, sometimes not. if that doesnt help. PM me or Reply in this Thread and I will help you troubleshoot the problem (This Helped for me, so I'd thought I'd share it ) Good Luck fragging! Dummy!
