Dear all,
sorry, but I need to come back to this - I still don't get the theme installed on my instance.
Can anyone give me a hint here?
In my overview of "purchased" licenses, I have two different users:

One user holds the trial license I had used initially. This license, I can "register". But that's no good as it has expired.

The other user holds the purchased "real" license - but it can not be registered: the radio button is greyed out.

What am I doing wrong? How can I use the purchased license?
Thanks and best regards,
Jan
Things get even stranger now:
I have installed it with the Trial-license (as the trial user) - and pooof: it works. Do I have the trial license running again now even though it's expired? Or the real one?
"License Manager" indicates the real one, but why couldn't Install that then?
Strange, but at least it's up and running again...
