The Battlefield error code BF-PB means PunkBuster, the anti-cheat software used in Battlefield games, has kicked you from a multiplayer server. This usually happens when your PunkBuster installation is outdated, corrupted, or not running correctly — not because you actually cheated. The good news is that in most cases, this is a software issue you can resolve yourself in just a few minutes by updating or reinstalling PunkBuster.

Frequently Asked Questions

Does BF-PB error mean I was caught cheating in Battlefield?
Not necessarily. The BF-PB PunkBuster kick is very commonly triggered by an outdated or corrupted PunkBuster installation rather than any cheating activity. Many legitimate players encounter this error after game updates or Windows updates that interfere with PunkBuster services. Follow the update steps in this guide first before assuming your account has been flagged.
Why does PunkBuster keep kicking me even after I update it?
If PunkBuster keeps kicking you after an update, the most likely culprits are your firewall or antivirus blocking PunkBuster's network communication, the PunkBuster background services (PnkBstrA and PnkBstrB) not running properly, or a corrupted game installation. Make sure both services are set to start automatically in Windows Services, and add PunkBuster as an exception in your firewall and antivirus software.
Is PunkBuster still used in Battlefield games?
PunkBuster was used in older Battlefield titles such as Battlefield 3, Battlefield 4, and Battlefield Hardline. Newer Battlefield games released after 2021 have transitioned to EA's own anti-cheat solutions. If you are playing an older title, PunkBuster is still actively required for those specific games on PC.
Where do I download PBSetup to fix the BF-PB error?
PBSetup is available for free from the official EvenBalance website at evenbalance.com. Always download it directly from this source to ensure you are getting the legitimate tool. After downloading, run it as Administrator, add your specific Battlefield game, and click Check for Updates to install the latest PunkBuster files.
Can I play Battlefield without PunkBuster installed?
On most servers for affected Battlefield titles, PunkBuster is required and you will be automatically kicked if it is not functioning correctly. Some community-hosted servers may have PunkBuster disabled, but the majority of official and popular servers require it. Your best option is to get PunkBuster working correctly rather than trying to find PunkBuster-free servers.
