One Fence has disappeared

One of my 3 fences on my desktop has disappeared.  The files are still on my desktop (if I used file explorer) however are invisible.  I've uninstalled Fences and reinstalled (of course, it immediately remembers two of the three fences and sets up).  I have created a new fence and tried to copy the files over to no avail.  HELP!  Have been using Fences a long time on several computers have never had this problem before.  No one seems to be able to fix it.
