I was having an issue with my hard drive so had to uninstall then reinstall everything, including FS9. After reinstalling the 747, the com raidos dont work. They're not even on.I start with the default cessna, turn the power off, leave the avionics on, then change to the 747. I've been doing this for a while and there were no problems before. Any ideas?Goran

Have you tried loading the default Cessna and leaving the motors on, then switching to the 744 and using the PMDG menu to load the Cold and Dark cockpit?

Yes, I have tried the default cessna, left it running and then changed to the 747. I left it as it was, everything running but radios are still off. Its very unusual.Goran

Its very unusual.Goran:There's one thing I can think of, considering the fact you've already re-installed, and that is rename your current FS*.CFG file and let it build a new one. Sometimes going through that process will do the 'trick.' It appears the 747 re-install is missing something. Did you install the latest patch?Ron_CYEGhttp://www.precisionmanuals.com/images/forum/pmdg_pf.jpg

Don't load the Cessna first, Load the 744 first from the create a flight menu, when positioned at the gate use the
