I'm having trouble with my mission... I'm trying to play a mission but as soon as I press play/start it just leaves me on the map still waiting to load or something... Is it a bug or is it a issue the devs need to deal with or Is it because me configuring the Campaign?

I already completed the campaign many times. Last time I played with cheats because for fun as I already played without the cheats. But this time I'm trying the Air and Sea battlegroup in the campaign and I keep trying to play a mission but its not letting me in the game so...

Help? Or can someone else explain if they also have the same issue?
