Maybe the solution; https://www.fsrealwx.de/index.php/forum/bug-report/1040-error-waiting-for-fs
I have had the same error, "waiting for FS" never ending...
Found this reply from SilloAdmin at FSrealWX forum, bug-report; NOAA weather should be up and running again.
Aha!! I opened FSrealWX-lite options - general, and unchecked VATSIM checkbox - changed to NOAA checkbox. Suddenly the program start loading weather stations.
Seems working..
