Hello,
You can try to reinstall my add-on (make sure to export your dials to a file first).
I haven't made any changes there for a long time so things should work normally.
Feel free to contact me to my support e-mail if it didn't help (of if it helps).

Also in a near future I will release a big upgrade that will fix some small issues with auto-reload and thumbnails generation.


Best regards,
Juraj Mäsiar
