It messed up the doors on my 777 too, because its not recognizing door being open already and all it keeps saying is open Door #1 or Door#2 depending which one I had set too my main door.. Which on 777 or even 757 is usually the 2nd door is your Boarding doors on the bigger planes..
It's not possible the update could have any effect on recognizing the airplane doors, since that is only controlled your airplane customization, which overrides the one from GSX.
Your reference to "Door #1" or "Door #2" is surely not accurate, since by default GSX will use the term "Exit 1" or "Exit 2" if the airplane is NOT configured and on the PMDG 777 ( you don't say which one it is, so I'll assume is PMDG ), which has a stock custom configuration that comes with GSX, the doors would be called "L Entry 1" and "L Entry 2", while on the Captain Sim version they would be called "Main Passenger Door" and "Second Passenger Door".
Assuming you meant "Exit 1" and "Exit 2" instead of "Door #1" and "Door #2" ( unless you customized the airplane to call them exactly like that ), it seems the problem is caused by either your own custom configuration having a problem, or the airplane not recognized at all, which usually happens only if the airplane is not supported internally, or when the developer release a new variant that comes in a new folder, which is common with Captain Sim for example.
