Is there a secret to chamming?

I just got chams to work today. And Everytime I turn it on. CA will close out within minutes. I noticed that it takes longer and longer each time to close out. But it is still annoying. Is there something I am doing wrong?

did you update before you used the chams and are you shure what u are using works

WHERE did u get the chams from? i havent seen any working chams yet....

there is a thread called "Chams Unpaatched 4-12-09" or something like that. The chams work for 5 minutes or so, then the Game kills itself.
