how to deactivate punkbuster in raven shield and athena sword ?

[genjutsushi]

I've bought raven shield and athena sword.they're updated to version 1.56 and 1.02. I tried to play on lan with a friend.
As i have only 1 game, I make a 1:1 image loaded on his pc with alcohol, it works, no more asking for the 2nd disc but when he connects on the server, punkbuster say that he has the same key as mine and he's kicked for 2 minutes.
Is there a way for punkbuster to be deactivating or not checking for the cdkey when he wants to play or something else ?

thanks for any help
