RESTRICTION: Service Communication Failure: Pnk Bstr Any ideas???? (First solution makes sure Punkbuster is running as administrator, this fixes a lot of problems on Windows.I used to get this error with APB Reloaded on my old pc - It's a Punkbuster issue rather than AC3. Second manually updates Punkbuster as sometimes the initial download and install doesn't complete correctly, or Punkbuster doesn't auto-update correctly, but it doesn't give a failure message) 1.
Scroll down to Pnk Bstr and Pnk Bstr (These are past the folders and in the list of files and applications) 3.
Right click on each of these and select 'Properties', then the 'Compatibility' tab 4.
Click 'Change settings for all users' (Windows may ask permission for admin privilages to do this, click ok' 5.
In this case, the game will usually kick you from servers if you are running an old version of Punk Buster for the game.
To update the version of Punk Buster for a specific game, download from their website.
