I accidently deactivated my 777 aircraft. When I reinstalled the aircraft + liveries, I can load the aircraft but no switches work. When I look at the aircraft, the landing gear also doesn't show (but the aircraft body does). When FSX loads the 777 it asks for the activation code (which I enter). It tells me the aircraft is activated, but when I get into the flight deck, the displays are dark and no switches work. Any suggestions?
