We are aware of a number of players getting kicked for "PB INIT FAILURE" after tonight's update. In our testing with these players, we're finding that many have security software or a firewall blocking traffic on UDP port 28962 which must be open to communicate with our COD4 update masters. If you are getting kicked after tonight's update, please either temporarily disable your firewall/security software or configure it to allow open traffic on UDP port 28962. This will allow your PunkBuster to update to future versions. Alternatively, you may manually update by using PBSETUP.
