Waterfall plugin not working

The waterfall plugin stopped working. When I want to see the themes list in the Waterfall plugin I only get e spinning wheel )on two computers). The plugin tells me, no theme is installed, but all themes are in place as you can see in the screenshot

Anybody has a solution…?

Works for me with latest 7.2 beta 7.

Here no success with the latest beta :frowning:

Also works for me with the latest beta, have you checked the Inspector to see that the registration is still active?

As far as I can see, Waterfall is not referring to the directory

~/Library/Containers/com.realmacsoftware.rapidweaver/Data/Library/Application Support/RapidWeaver/

but to

~/Library/Containers/com.realmacsoftware.rapidweaver/Data/Library/Application Support/RapidWeaver/RapidWeaver/

for some reason. I do not find an option to correct this
