I have been banned by PB, the point is this, I to I bought cod4 on steam, and so far had no problem. punkbuster stopped supporting Activision, so several people on steam forums links left to hang punkbuster to an older version. because really if I update punkbuster to latest version in the game list of the cod4 punkbuster does not appear. I wonder if there is any way that you remove my ban or at least tell me how I can fix. because it is very unfair to have a steam bought cod4 and not able to play. My name in-game is "Cristina 2015"
