I am using the BattlefieldVietnamv1.21SinglePlayerMultiplayerNoCD FixedexeModFixedEng
and the game works fine all together, but when trying to play online, i am unable to join any game running Punkbuster, when i try to join it says that its not enabled, so i enable it and then it asked for me to insert the BFvietnam CD, therefore unable to do it.... Is it possible to play online with this crack, or not? sorta new to this type of thing because the only reason im using it is my other copy got damaged, if anyone can help please respond, not sure if its something im doing wrong or what ! thanks
