OK, a different tack. The Cumulus FTP Progress window stayed open 20 seconds before displaying "Connect Timeout" so that should be long enough.
What could the host company have changed overnight with a flip of a switch that could cause Fling, Filezilla, Cumulus, GRLevel3, and L2K to suddenly cease providing FTP data? Am I being paranoid to see everything shut off and yet the host tells me that for a $60 fee they can fix it.
