Sorry for delay.
I made some tests yesterday trying to understand what's going wrong. It seems I solved the radio pushbutton in VPilot : first I noticed that the config.xml file was somehow vanished in VPilot folder ! Don't know how to explain that. I had to reinstall VPilot , create a new config.xml file, but that wasn't enough. Then I reconfigured the Yoke in windows and recalibrated it. Now it is recognized by Fsuipc and so I could assign the right button, as before.
But the game is not over . Made two flights : first one ended up in ctd after 10 minutes from takeoff and the second was a ctd just after touch down (after a terrible approach with sudden lags, stutters and stops, both in scenery and in Prosim ).... a real frustration !
The Windows reports are quite useless to investigate issue involved . Generically referred to Msfs.exe , Couatl.exe, Fsuipc.exe, ntdll.... etc... crash.
I saw a error report in first ctd related to RAM ....
Who knows ?
