Sorry to hear about the problem you are having with PunkBuster. Normally when errors like this occur, it can be a good idea to reinstall the PB setup. Please follow the instructions below and then try to play the game again:
1. Open Origin and Right Click on the Battlefield 3 and Choose "Repair Install"
2. Once repaired, go to this location: \Origin Games\Battlefield 3\__Installer\punkbuster\redist
3. Reinstall PB services
4. Reinstall PB with PBsetup.exe http://www.evenbalance.com/?page=pbsetup.php
Thanks.
