1. - Restart your PC, or use task-manager to close down any FG running in background.
If that do not work:
Find this folder:
c:\users\[your win login name]\AppData\Roaming\flightgear.org
Appdata is hidden, you you must set windows file explorer to show hidden files.
Inside that folder, check for a file called Fgfs.pid, and delete it.
Not 100% that file is still used in latest FG version, but it might be there. If its there, delete it.
If you do not have that file and you tried restarting your PC, then I do not know.
