Getting a Mezzmo error 2.1.4.4d when launching the add-on. I can configure no problem, and it installs without error, but when launching from 'Videos' I get the error message and cannot see a list of files

Hope this error log helps. This is from a Kodi Windows 10 install, but I see the same behavior on my Shields.
