Just for fun I re-entered my call sign and password into Nova for Space-track.org and now I can download the keps all OK.
My callsign and password were already in Nova but for some reason they wouldn't work.....I had to re-enter them into Nova and now the bloody program will download the keps....ain't computers and software great??? (grin)
OK...no more dumb questions for a while.
