Something on your computer is still blocking/conflicting with the PB services.
I'd like for you to give me a list of your currently running processes. To do this:
1. You'll need to download 'tasklist' from the following site:
http://www.computerhope.com/download/winxp/tasklist.exe
2. Start the game, minimize it.
3. Click "Start" => "Run" => type "cmd"
4. Type "tasklist /SVC > tasks.txt"
This procedure will create a text file with a list of your current processes. The text file can be found at"C:/Users/[your user]/tasks.txt". Paste the contents of this file into a new note on this ticket (you may need to put two notes or more if you have several of them).
