Battlelog BF3 co op error

Me and a friend tried to play BF3's co op mode and it didn't work for whatever reason (Battlelog should be discontinued in my opinion, way too glitched, fundamentally flawed).

Now me and my friend cannot play Co op because battlelog detects us as already in a game with each other, we've both logged in out of origin, battlelog, played in other game modes, played single player, even restarted computers, disconnected the internet, repaired the install, but it seems to be an error on battlelog's side.

This could have all been mitigated by putting a server browser IN the game, without it we're left floundering and frustrated.

Any help would be appreciated.
