Welcome back, stranger!
Thanks for the update which took a bit of switching between providers to get the 'Update' button to be enabled. Basically what I had to do before selecting the IMDB provider in the list was to chose a different provider then go back to IMDb to get the update option. After that happened, I was able to proceed as in your intructions.
It is good to have IMDb back as an option although I haven't tested it yet.
