If those statements held true in my case, I wouldn't have needed to uninstall and reinstall it.
I can only repeat and confirm there's zero difference between uninstalling/reinstalling and just running the FSDT Live Update.
The fixed file is the main airport .BGL and that's NOT EVEN INCLUDED IN THE INSTALLER, haven't you noticed the installer runs the FSDT Live Update and downloads the missing airport .BGL after having verified your license ?
That's why it's impossible to see any difference between reinstalling/uninstalling and just running the FSDT Live Update because, the only way to get the fixed file was...running the FSDT Live Update, which the installer does in the exact same way you do manually.
