I've been hearing a lot of people having PB (PunkBuster) problems in games lately. If you have been having an issue please try the following steps. 1. Make sure your PB is up to date. You can do this by going to www.evenbalance.com and downloading the pbsetup application. Once you do this follow the directions on the website and you should be good to go. This will assure you have the latest PB files. 2. If step one does not work you may be running a 64-bit OS. For some reason PB has issues updating in game with a 64-bit OS running. This means that in some cases you have to run pbsetup each time before gaming. Yes its a pain but it does work. Evenbalance knows of this issue and has been working on it for sometime now. They have made some progress but as new games come out the issue reemerges. 3. This is something I do as a final step to PB "failing to connect" during game play. It seems to fix more than anything else. Why I don't know but who cares! It works. Step 1: Quit all applications. Step 2: Open your "Task Manager" by hitting Ctrl+Alt+Delete. Step 3: Find the process "PnkBstrA.exe". Once you found it right click on it and a menu should open. If done properly it should look something like this... Once the menu is open select "Open File Location". Step 4: Once you open PnkBstrA.exe location in the C: you will need to right click it again in the new window. This will bring up another menu. Once the menu is open select "Properties". This will open up yet another window. If done properly it should look something like this... Once this window is open click on the tab "Compatibility". In this tab there a check box in the privileges section. In this section you have the option to "Run this program as an administrator". Turn this option on. Step 5: Repeat step 3 and 4 for the same application "PnkBstrB.exe". Step 6: Close all windows and restart the computer. Once this is done try playing the game you were having an issue with. You might have a nice surprise! Tip: PnkBstrB.exe is located in the same exactly place as PnkBstrA.exe. When you change the rights on one just look for the other one in the same folder. DO NOT MESS WITH PnkBstrB.xtr. Ill update this post with more fixes as I hear about them. In the meantime happy fragging! UPDATE: Recently I got a new error. When playing Bad Company 2 it would kick me from servers with the following error "service communication exeption: punkbusterb.exe failed to initialize". To fix this issue follow these steps: 1. Go to the BC2 application folder. 2. Locate the "pb" folder. 3. Delete the content of the "pb" folder but DO NOT delete the folder itself. 4. Now you can manually update the PB using this. After that follow the directions above this update.
