I recently bought the PMDG 747-400 and i just realize how hard that plane is to handle...i'm trying to learn since cold and dark but some switches shows on even on that panel state.I'm trying to save my own panel state with everything off and i get a message(cannot create file})...so much frustration and i cant even take off yet...the thing is i wanna learn everything and enjoy this product.......help Please...Thanks.....
