Can anyone help me?

[SGTDUNK]

Ok, I am starting to get riled up. Starting today, my computer has been giving me messages about my Punk buster not loading, and I therefore get dumped from the server at the beginning of a game. I have re-installed it, and tested it, and everything comes up good-to-go, but I still get the error and dumped. Does anybody have any ideas as to what is happing to my box?

Here are some known issues with PB. One of these may help you.

COD4 Issues with PunkBuster

I cant enable PunkBuster. How do I install it?
Insert the COD4 dvd into the drive and browse it. Run pbsvc.exe to install PunkBuster.
You may need to reinstall the game and choose to install PunkBuster this time when it asks you.

I got kicked for 'PunkBuster Init Failed'
This usually means your punkbuster isnt upto date. Get pbsetup (http://www.evenbalance.com/index.php?page=pbsetup.php) run it and add Call Of Duty 4 to the list of games. Then hit check for updates. This should fix the problem.

RESTRICTION: Unknown Windows API Function[131133]
Apparently using the built in interface by steam in COD4 is cheating. Atlest it is according to punkbuster. To get rid of this error message open up steam and go to [ Settings -> In-Game ] and uncheck the Enable Steam Community In-Game button

RESTRICTION: Service Communication Failure: PnkBstrB.exe handshaking failed.
If you get this message it because your Punkbuster files are corrupt, missing or simply forgotten by PB. To fix this you should reinstall the punkbuster service module and reupdate PB. To do this you can go to your steam/steam apps/common/call of duty 4/PB/ folder and run pbsvc.exe to reinstall it. After that you should re-update it by using the pbsetup.exe.

I get 'PB Client in Distress' error messages
This is a problem with the PunkBuster authentication servers. Theres nothing you can do about it.

I get kicked with 'Ignore queries #9006' message from punkbuster
You have to open UDP port 28962 for Punkbuster Update.
You can manually update with 'pbsetup.exe' from the Evenbalance (http://www.evenbalance.com/) website.

I appreaciate the help, and I will try to update it first, as re-installing games takes forever on vista. Thanks again!

Hey, I dont know if you are still having issues with pb or not but.. I did as well, in BF 2 and CoD4. I run vista and this is what I ended up doing to fix the problem.
I had to download the pb file, http://www.evenbalance.com/index.php?page=pbsetup.php (right click the link and save target as do desktop or somewhere you will remember) manually drop that .exe file into the main pb folder of the game that I was getting kicked from, and then run it from inside that folder. I hope that helps.
For some reason when you update pb with vista it puts everything into the wrong files. Manualy putting the .exe you saved to your desktop, into the pb file inside of CoD4 pb folder corrected that for me. Good luck.
