Buck-I've had that happen before, and I've just deleted the preferences user/library/preferences/com.heat.meteo.plist AND the cache user/library/caches/Meteorologist/folders numbered 01, 02 etc
Ok. I deleted both items. Still a no go.
I Don't know if this helps or not.
But when I install from scratch.
There is one city already listed.
That city is Cupertino, Cal,.
If I delete it or not. I still can't load the city I want.
It continues to tell me ( not found ).
