Punkbuster

Punkbuster works with 64bit win 7, you will need to update your files. Goto evenbalance and down load the setup tool and run it. If the problem keeps happening you might need to contact the server admin to update their files on the server too.

Yep, unfortunately not all servers have upgraded their punkbuster files yet (no need up to this point).
With Win7 availability, as more and more people (and servers) upgrade to the new OS you will see pressure on Punkbuster (and other Software) pretty much forced to update and fix these issues. May take a couple of months (or less) but these issues will be fixed.
