When I try to open the main doors with Shift+E it shows the green bar saying main door opening and closes by saying main door open but when looking at my external model and on my EICAS drs there is nothing open HELP PLZ!!!!!!!!!!x(

As documented in the manuals and FAQ in PMDG Ops (http://ops.precisionmanuals.com/wiki/PMDG_747-400_FAQ#How_do_I_open_the_doors.3F)How do I open the doors?The 747-400 and 747-400F use custom code for the door logic, as such the default SHIFT-E commands will not work. Go to the PMDG menu within MSFS and then the General | Keyboard Assignment option. There you will find a category listing for Doors 747. Assign your desired key combinations for each of the doors and exit the menu. You will now be able to open each door individually according to the key combinations you assigned.
