RESTRICTION: Service Communication Failure: PnkBstrA.exe

I got the RESTRICTION: Service Communication Failure: PnkBstrA.exe message.
I finally fixed mine after reading lots of forums, i did a few of my own things, some probably not needed, and others probably noobish, but in the end mine works!
i did:
1. Open windows firewall
2. click advanced settings( on the left) and then inbound (also left)
3. Find PnkbstrA.exe and PnkbstrB.exe (if you have two of both, its fine)
4. right click on each of them>properties>programs and services
5. make sure that "all programs that meet the spesifications" is checked
6. then go to the "Advanced" tab and check all 3 boxes. Domain, Private and Public.
7. REMEMBER TO DO THIS FOR ALL PnkBstr Files. then save and quit.
8. Go to C:\Program Files (x86)\Origin Games\Battlefield 3 and delete "Pb" folder.
9. go to these 2 links:
http://websec.evenbalance.com/downloader/download.php?file=1
http://www.evenbalance.com/downloads/pbsvc/pbsvc.exe
10. download and install both
11. Run Pbsetup.exe (the first link)
12. add a game (eg. bf3)
13. check for updates.

This should help

PS: for some reason i can no longer launch bf3 from chrome after doing this so i used firefox. (this is not the first time i have done this, although the first time was not the same error.)
