Punkbuster seemed to have gone bananas on me last saturday. Every time I connected to a server, it disconnected after approx 2 minutes, with a whole host of different reasons, most of which seemed to indicate that it couldn't connect to the Punkbuster master server.

Punkbuster seemed to have gone bananas on me last saturday. Every time I connected to a server, it disconnected after approx 2 minutes, with a whole host of different reasons, most of which seemed to indicate that it couldn't connect to the Punkbuster master server.

After two hours of frustration and faced with the possibility of a re-install (my rank!!!) I believe to have found the solution. It's a quick re-install of Punkbuster following the below procedure.

1) Locate the 'pbsvc.exe' file on the COD4 disc (root directory).

2) Run this program and choose the option to uninstall.

3) Once uninstalled, locate the 'pb' folder in the COD4 folder on your hard drive and empty it, but keep the folder.

4) Re-run the 'pbsvc.exe' program on the COD4 disk and choose the install option.

5) Once done, you will need to go to the Punkbuster website and download the updater tool (pbsetup.exe)

6) Update COD4 using 'pbsetup.exe'. Found Here That's it!!

By the way, don't expect any entries in the pb folder until you have updated.
