My solution was pretty lame...
When starting a multiplayer session to a non-punkbuster enabled server I had the time to notice the gameplay settings.
The >Allow Punkbuster< Setting was set to >NO< by default.... which was causing me to disc everytime.
Changing the setting to >YES< worked for me


是不是说他发觉自己的游戏客户端里的PB设置默认是关着的？然后改成激活就可以了？
如果这样，那对我也就没用了哎，因为貌似我游戏客户端里默认PB是开着的……

是的

泪目啊……我到EA论坛去看了，估计是64位系统的PB上的BUG……
一老外重装过PB，重装过游戏，重装过系统……统统的被枪毙掉了……他已经崩溃了……
