First, do this steps: http://help.ea.com/en/article/battlefield-4-punkbuster-troubleshooting/ .
Also, try this additional steps, if the above does not work:
1. Open windows firewall
2. Click advanced settings( on the left) and then inbound (also left)
3. Find PnkbstrA.exe and PnkbstrB.exe (if you have two of both, its fine)
4. Right click on each of them>properties>programs and services
5. Make sure that "all programs that meet the specifications" is checked
6. Then go to the "Advanced" tab and check all 3 boxes. Domain, Private and Public.
7. REMEMBER TO DO THIS FOR ALL PnkBstr Files. Then save and quit.
8. Go to C:\Program Files (x86)\Origin Games\Battlefield 4 and delete "Pb" folder.
9. Go to these 2 links:
http://websec.evenbalance.com/downloader/download.php?file=1
http://www.evenbalance.com/downloads/pbsvc/pbsvc.exe
10. Download and install both
11. Run Pbsetup.exe (the first link)
12. Add a game (eg. bf4)
13. Check for updates.Also, try to disable your firewall if it does not work.
Please try the other steps then, as they may solve the problem.
Also make sure to do a clean boot of your windows program, if they all dont work and you get the same error message.
