With my new B777F from PMDG I get the message in cold and dark startup situation, that I need to stop the engine, otherwise no ground services available. The engines are off, I tried it several times. PMDG wrote, that it is a GSX-problem and FSDT is working on it. With all other aircraft (Fenix, FBW), I'v NO problems. How far is the fix to resolve this problem?
