punk buster multi hack.........

PunkBuster software running on game servers and also on the computers of connected players during gameplay is continuously validating each player with respect to avoiding violations. A violation can be raised by PunkBuster for various types of things depending on how each Server Administrator chooses to configure PunkBuster on the game server. The various categories of violations are explained below.

When a violation is raised, PunkBuster announces this violation to all connected players in the game and then saves information about the violation into a PunkBuster log file on the server. In most cases, the player associated with the violation will also be removed from the server for a few minutes. It is up to each Server Admin whether or not to permanently ban players for violations raised by PunkBuster.

Note that some servers are non-dedicated. That means that one of the players is running the game server while also playing inside the game (known as a localhost player). If PunkBuster raises a violation on such a localhost player, the violation will be reported, but the localhost player will not be removed from the game. The other players will be alerted to the fact that PunkBuster is foregoing the kick due to the violation being raised on the localhost player.

Steps to resolve violations are given below with each violation category. Any player who has problems resolving a violation should fill out a trouble ticket here for assistance. When requesting assistance, be sure to specify the violation number raised and give as much additional information as possible.

You can go to Pbuster's site and open a trouble ticket if you feel you are getting the error for no reason...
You may try disabling anything that is running in the background....
Maybe update or patch the game if it is not up to date....And Punkbuster as well...
Have you downloaded any MODS for the game?  uninstall those?

Worst case scenario try uninstalling and reinstalling?
