Problem to move pics


I'm using SmartFTP v1.5 and I have problems to move pics from my computer to the server of our homepage.
After trasvered a picture I get the information:
SSL/TLS Interner Fehler (Fehler = 0x869f242f).
Das Token, das der Funktion

Please upgrade to SmartFTP 2.0 before reporting problems, version 1.x is not supported anymore.
