Because Stardock released the game a day early, the multiplayer servers that are online are still the servers (or likely server) from the beta. Those are being switched out right now, so multiplayer is spotty at best right now. I would say don't worry about the update for now and check in on it tomorrow. The single player skirmishes will hopefully tide you over 
And I should say, Impulse is where the update will show up.
