The German site was the trick, uninstalled and reinstalled using the v4 installer....I didn't see any difference in the installation. Thank you very much! Now the issues are the ADF simply doesn't turn on (major) and neither does the transponder (minor) And there seems to be a brightness issue but I need to read more before I squawk to loudly as this might be operator error. I see that the ADF issue is a carry over from previous versions. I am surprised that Aerosoft feels comfortable selling a defective product. The plane flyies fine...and VOR Navigation works fine...I don't use the GPS.
