Have tried with Firefox - failed. I don't know the reason, but I cannot instal battlog on this browser. Also it shows me the same error with not started Origin, although it's running.
I still hope for the best. Anyway, thanks for answer.
close your browser completely, start origin and then open your browser.
That seems to work for me when I encounter this message.
When you switch to Firefox, try to turn the option to use plugin-free game launching off. It will allow you to launch the game with use of Battlelog plugin again (you might need to update it though), thus fixing that particular problem.
Unfortunately this happening no matter which browser. It all started since the latest patc.
