Punk Buster File Downloads This brings us to one solution; user-to-user sharing of the latest downloaded Punk Buster files because there is no other way to get them at this point.
If you have an Apple computer many games provided by Nosteam will not work on your device.
well fear no more, if you are experiencing this problem it is simply because your Punk Buster didn't update with the game like it should have.
this can be caused by downloading the updates off Xfire and Fileplanet.
answer my own question, the appdata pb files seems to be built from the files in the game directory pb folder.
I deleted the appdata folder and then extracted the pbbans files into the game directory.
