How to fix PB
If ever you are having problems, with PunkBuster, the first thing you should try is, before connecting to a server, type "/pb_system 1" then "/pb_sv_enable" then "/pb_sv_update". This should fix most problems, If you still have a problem with punkbuster after doing this, contact Evenbalance (the makers of PB) at http://www.evenbalance.com.
