pnkbstrb.exe stopped working

found this procedure:

"Service communication failure... and something about pnkbstrb.exe.

Well i have solved the problem and wondered if anyone else had a similiar problem.

If so then download the following
▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼

1-pbsetup: Even Balance Technical Support - Download

2-pbsvc : http://www.evenbalance.com/downloads/pbsvc/pbsvc.exe

▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼

1st... Open pbsvc and and click uninstall... Then open it again and click install(be sure u are running as administrator)

2nd... open pbsetup and add your required game... then click look for updates.

once you have done this then click start and run services... look for pnkbstrb... if its there then everything is cool.

if you still have problems the open services and make sure that it is set to automatic.

Worked for me

Same issue as OP. Played a couple of games last night without any issues. Now, I get the same error message. I click Okay, then leave bf4.exe running. It loads to the Map loading screen after 3-5 minutes. The game loads in 20s.

Here's the crash report dump: http://www.sendspace.com/file/m0bu0h

Also, the blue ribbon at the botton stays blank until the game loads. It goes straight to "PLAYING BATTLEFIELD 4 BETA ON PC".

EDIT: I re-installed PB and the error stopped. I ran the installer as administrator.
