Fences Backgrounds - Windows 10 - Uninstall & Reinstall

Since my last Windows update, Fences does not display the shaded background around my fences. When I look at the screen snapshots, the backgrounds are there, but not when I look at my desktop. How can I get them back? Also, when I double-click my desktop I get a message that Fences needs to be reinstalled, although in a few seconds the full Fences menu appears. I re-downloaded the Fences installer and ran it thinking I'd overwrite the existing install to preserve my settings, but it keeps stopping saying that the uninstaller file is in use so I can't continue. Is it possible to uninstall and reinstall and preserve my settings? If so, how? Thanks.
