While PunkBuster is designed to update itself, there can be an error and manually updating via PBSetup is recommended.
Occasionally, you may receive various errors regarding PunkBuster Services not running. Some other software programs such as virus scanners, firewalls and Internet security software packages are suspicious of any new services and kernel drivers when they are first released. Some of these will block PunkBuster components thereby causing the "Losing Key Packets" kicking. Until these various packages are updated to correctly identify PnkBstrA.exe, PnkBstrB.exe, and PnkBstrK.sys as components of the PunkBuster Anti-Cheat System, players who experience PunkBuster kicks due to these conflicts need to either manually adjust the settings of the other software running on their system or disable the other software while playing on PunkBuster enabled servers.
Make sure PnkBstr.exe is on your exceptions list of your firewall/anti-virus software to ensure it can communicate properly with the PunkBuster servers. You can check your anti-virus/firewall software manual for instructions on adding exceptions.

Scroll through the list and find PnkBstrA and PnkBstrB. If they are not running (Check the Status column), right click each and select “Start”.
