Want to play again but cant get past punkbuster.

So I finally decide to get back into ETQW and I cnat play for more than a min cause of Punkbuster :(
I checked online and its because the game is no longer supported by punkbuster and cant update any more. I checked online there was a work around with a Legacy pack, I tried it but it still kicks me.
If anyone knows how to fix this it be much apreciated, want to get back into a great game :)
