I just installed v16 on one of my laptop systems and imported the v15 CSV profiles from my desktop, as a test I'm trying some of my sites and on the v16 system I get an error "Unable to resolve "ftp://instructor.xxxx.xxx" ." The same profile on my system with v15 works. I looked in the help file
OK I resolved the 11001 error which turned out to be a Host not found error. I had entered the Hostname name as "ftp://instructor.xxxx.xxx" I changed this to "instructor.xxxx.xxx" and now FTP Voyager will make the connection. It would have been helpful if this information was in the help file.
