Can't complete installation.

So I downloaded Quake Wars through Steam today and I've just went to play it and it got through the usual DirectX installations, but after it gets stuck installing PunkBuster. The PB window pops up, says everything is fine then the Steam window just reads "Installing: PunkBuster Anti-Cheat (1 of 2)". It's really bugging me now, I want to play.
