I have the same problem. From Origin I hit start game, cloud sync bar goes, then im prompted to allow web helper. I hit yes (or no) and nothing happens. No battlelog page or game launch. If I log into battlelog manually, I can see the servers, but if I click to join one, it has the cloud sync bar go to 100% again, then web helper yes/no prompt again. I hit yes (or no) and it says joining game, but nothing happens... The origin page pops up from behind though as if I am supposed to do something else, but all I can do is hit "play Game" again and the same cloud sync bar goes and web helper yes/no prompt happens again, but no game start... I cant play BF4 at all!!!! This happens on IE (microsoft edge) or firefox 64. Same thing.
Windows 10, Nvidia 970.... always worked before. This update Jacked me
