Working through the update.
For others.
On my Mac it automatically unpacks the .gz on download. Be mindful as that will fail upon upload.
I did not notice at first. Deleted the html and restarted. That brought up a new page for missing files. That new page has a better more obvious design for uploads.
If you find yourself confused on what to upload, delete the html and restart. The page that comes is much more clear for the non literate. .
