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

10. Download and install both
11. Run Pbsetup.exe (the first link)
