Hi, guys.I've just installed the PMDG 737-800/900 (I have the box version, bought in 2005). After starting FS (version 9.1), I select this aircraft, then start flight. All the screens in the panel appear black and almost all the switches don't work. The engines are running. Everything was file on my old PC, which run XP 32 sp2.I've used search, but unfortunately didn't find any solution.I would be really grateful if you help me.
