SmartFTP nach update: "502 Command not implemented." Was tun?

Liebes Forum!
Ich habe bei der Verbindung Humax iCord HD und Computer jetzt viele Monate SmartFTP in Verbindung mit DLAN ohne Probleme verwendet.
Vor ein paar Tagen dachte ich mir, SmartFTP auf Version 4.0.1118.0 zu aktualisieren.
Seither habe ich bei jedem Versuch, wieder auf den iCord HD zuzugreifen
folgende Anzeige: "502 Command not implemented."
Ich bin völlig ratlos und über mich verärgert.
Eure Hilfe wäre von einem Oldie (65) ganz dringend erbeten.
Danke!
