Olympus ORF files not transferring

I've been having trouble with SmartFTP for a while now, getting "stuck" and copying files over and over and over and... 
 
I worked with it today and it appears the files that do this are all Olympus ORF (RAW) files.  Sony Raw and JPG files don't seem to have a problem.  This is a new problem, but I'm using the same computer, so I believe there has been some change to the site I am uploading to.  On the other hand, although I've had the Olympus for a while, I used to take primarily JPG files rather than RAW with it. 
 
I'm using Version 4.  I've tried a couple of things including disabling transfer integrity in the favorite file for this destination, but it's still copying over and over.  I should say, sometimes it succeeds.  But if I queue up a lot of files and go to bed, in the morning I'll find it stuck on two files (my limit for this process is 2). 
 
This is a snippet from a log file.  You can see the file 20160114@145350.ORF repeating.  I don't know if there is information in the next line or not.

I can copy .ORF files other ways, for example, using freecommander, which is free...  I like the features of SmartFTP but I don't want to spend money upgrading when I can get this done using other tools.  This is very frustrating because I've used SmartFTP for many years, through two versions. 
 
Thanks for any suggestions for gettintg this working!
