"Failed to convert data connection to TLS" error using Older version works

Nov 19 '14 at 12:26

VC++ 8.0 SP1 application built using with Chilkat version connects but PutFile() fails. When built with older version (not sure of exact version but .lib is dated 8/20/2014) the PutFile() succeeds. Last Error and Session Log are below. Is there some new setting in that I need to set?
