Since that post was more than 1 year old, we included the fixed file in the scenery installer.
You should understand that, since we have a Trial version, we obviously have the best interest to show the scenery as updated as possible so, as soon a fix is found, it will be included in the installer.
I'm posting the file again for convenience, here but, if it's more than 1 year you haven't updated JFK, perhaps there might be other thing you were missing.
