PnkBstrB.exe heartbeats stopped failure, again..

I started recently playing some public ET again. All went fine in the start and so, but like 1 week after this problem showed up:

"Server disconnected - Punkbuster kicked player "retsev" (for 0 minutes) ..
Restriction: Service Communication Failure: PnkBstrB.exe heartbeats stopped"

I've been trying to fix it, but nothing seems to work. I never before had a problem with this hearbeat thing, so it kinda surprices' me.

I tried already to reinstall ET totally, and updating punkbuster over and over again.

When I look at my taskmanager while playing ET, I can see PnkBstrB.exe starts and runs for like 1 min. or smt. Then it gets removed from the Taskmanager and is totally gone, and then I ofc. get kicked by the server.

I tried also to run service.msc - Where I set it to auto, and aswell I went changing that if the service didn't work, it would restart. But that didn't help either.

So I'm looking for anykind of advice, anything! I will send a pack of cookies to the guy/girl that can help me solve this problem !

Thanks :'(
