Cannot access Designs Gallery via Content Catalog

[kawabunga]

I am using Xara Designer Pro X 11.2.5.42127 (x64), trying to create a web page via Contents Catalog and wish to access contents I had purchased previously, but when I click on "File>New from Content Catalog", I get a pop-up saying "The Designs Gallery must be enabled to import content."
But when I check in "Utilities>Galleries", I see that the Designs Gallery is already with a tick (and cannot unclick/click to make sure it is activated)

Then the whole thing loops, not allowing me to access the Designs Gallery.

What am I doing wrong (short of re-installing the whole app)?

(I have already submitted a ticket for this, but thought that there might be some forum users who might have the answer to this urgent problem).
