EvenBalance updated the Punkbuster client for RTCW today, 11/28. While the update should be seamless for most (PB phones home while you play and updates itself automagically), I noticed I was getting kicked off the server with "PB client distress" errors. I suspect this is because I'm on a Mac and EvenBalance never seems to be able to update their software without screwing something up in their Mac client.
In case any of you are seeing this too, Mac or Windows, there's a tool on the PB website you can download
here to manually update the PB client on your computer. This should solve the problem.
Hey, you're welcome.
