Re: Battlefield 4 Not Starting Game, but Showing Up As Playing.
I searched through other posts about this and found a solution.
Set your default browser to IE. (So BF4 opens it and logs you in)
Open BF4. So it opens Battlelog in IE.
Go to Settings (drop down from your portrait on the top right)
Go to Game Launch, change it to USE Plugin
Try to join a game (it will fail)
Exit BF4, close IE, enter task manager, kill any BF4 processes
Go to your Documents folder, Delete BF4 (this will delete your settings, but its not like they are doing you any good).
Load up BF4 again...
Join a server...
Success!
.... Or sort of.
Left a game, tried to join another, and it screwed up again. Deleting BF4 settings fixed it.
