I followed these steps and it did not work for me.  However, with slight modifcations it worked.  Uninstall the plugin as described. Reboot. Yes, reboot I know its annoying.  Then install the plugin as admin.  Go into chrome settings and confirm always on as described.  Reboot yet again.  Run Bf4 shortcut as admin and cross your fingers.  Might be worth double triple checking punkbuster is up to date as well.  See if you can load into the test range and then try a multi match if push comes to shove

I fixed this problem in firefox (33.0) by setting the battlelog plugic to 'awlays activate' rather than 'ask to activate'.

I also had to 'go online' in origin after restarting it.
