Suddenly, on all my aircraft the radio displays, altitude, speed, vs displays on glareshields are empty??????? Rest of the panels and displays work fine. anyone know what's going on?ricardo

sounds like you saved a flight or got booted with your avionics switched off. Try loading the default 747, make sure everything is turned on (it's pretty simple with that aircraft) then saving the flight, then try again. Good luck!billg

Thanks for the reply but that isn't the problem. The avionics work fine. But there are no digits on the comms and navs and (in the big jets) on the displays. Was working fine yesterday, the only change is that I installed the BAE 146 from Aerosoft, which, perhaps, overwrote a font I need to display these numbers?ricardo

funny you said that, I just did the same thing, let me check my other aircraft, brb...billg

I just solved my problem: uninstalled the BAE 146, then rebuilt the fs9 cfg. On loading FS9 I got a message: ",,,found incompatible sound.dll. do you wish to load this software or not?" When I click yes, no displays. Clicking no= displays are back.weird.ricardo
