when I play COD 4 online, I get kicked out of
punkbaster and I get a message that reads: mustang punkbaster kicked player mustang (for 0 minutes) RESTRICTION: service communication failure: PnkBstrB.exe heartbeats stopped!
what does that mean
PunkBuster is a major source of annoyance for most people , I kept getting the same message on Battlefield 2142. The way I solved it was to go into the location of the PunkBuster file that stopped working and create a firewall exception for it. Afterwards run COD4 as an administrator and see how you go.
