transfer queue idle, won't start


I've been using smartFTP for years and like it very much. I've just loaded it onto a new machine, however, and the transfer queue won't work. The transfer queue contains an entry, the triangle button has been activated, but no transfer occurs...It just sits idle. I've tried to reinstall the program just for the hell of it with no luck...All my other computers running smartFTP are fine. Do you have any suggestions?
