If you still cant activate game try repair and if not working launch from Origin library than go on BF battlers and install addon for Chrome- battlelog-web-plugin.
After that you will need to go on and launch game from there, no matter if you want to play single or multiplayer.
I was mad at EA because i purchased game and waited 4 days to activate and able to play but now i know that my waiting wasnt for nothing!
This for sure is my best gaming experience in my life, together with World of Warcraft, like 7-8 years ago.
p.s
Spell checker is very annoying and not helping for us non English language players, try to fix that EA!
