Today I finished installing my computer again to try to get my 2D main panel for all airplanes back. Both the C: drive (System) as the F: drive (FSX) were deleted (partition) before I created them again and installed the software. After the installation of FSX I was very curious to see if I had my main panels back again.
Unfortunately it wasn’t so, I still have got no main panels. When I am finished installing the rest of the software for FSX I will look into panel mania to see if I can still get something that resembles a main panel. If not, I will have to keep flying with a Virtual Cockpit until I have made the necessary equipment (mainly for the Boeing 737-800).
