Please try to repair your PunkBuster installation first:
- Head to the Battlefield 4 installation folder, C:\Program Files (x86)\Origin Games\Battlefield 4 by default, then find the _Installer folder.
- In _Installer, find and navigate into the Punkbuster folder, and from there, into the redist folder.
- Find and run pbsvc.exe to update or repair your Punkbuster installation.
If the above folders don’t exist in your installation:
- Head to punkbuster.com and click the Download PBSetup button, and select the option “For All Windows Games."
- Open pbsetup.zip, then run pbsetup.exe. Accept the EULA, follow the instructions, update PunkBuster, and then click Add a Game.
- In the drop down menu, select Battlefield 4, then Add Game, and finally, before trying to run Battlefield 4 again, Check for Updates.
If you are kicked from your game and receive the error, PunkBuster kicked player 'your name' (for 0 minutes) ... RESTRICTION: Service Communication Failure: PnkBstrA.exe),” the above steps will help resolve your issues as well.
More information can be found on the PunkBuster Battlefield 4 page.
