My System Environment:

Battlefield BC2 Beta? Yes
Microsoft Vista 32bit

Yes, I know there are many ways to fix this problem, but this is how I resolved it.
Keep in mind my other games also used punkbuster and those files are located in this directory:
c:\users\jacob\appdata\local\punkbuster
There was an empty folder inside this directory that was named BC2 left over from the uninstall of the Bad Company’s beta. Even after uninstalling the beta I think the full release of Bad Company 2 actually still looks in this directory for the punkbuster information.

Problem:

After joining a game the user is kicked with this error:

You have been kicked from the game. The reason is:Punkbuster kicked player ‘playername’(for 0 minutes) … PB INIT FAILURE (if this persists, visit evenbalance.com slick support to manually update PunkBuster).

Solution:

1. Go to the
C:\Program Files\Electronic Arts\Battlefield Bad Company 2\pb
   folder and delete everything inside the pb folder.
2. Now, go to the evenbalance site and download the pbsetup.
3. Run the pbsetup and choose bad company 2. It will now download the required files.
4. Once that is finished, copy everything inside the
C:\Program Files\Electronic Arts\Battlefield Bad Company 2\pb
   to
   C:\Users\<your user name>\AppData\Local\PunkBuster\BC2
5. Restart your computer for good measure.
