Package Generator delivers an empty folder

Hi, Just renewed my license in order to make easy use of the 'Package Generator'.
Reading through your documentation, I assumed that this generator assembles a number of files based on my choice of the (later to be renamed 'index.html'-file) html-file that fires up the website.

So I chose, as an example for this week, 'demo-branding-studio.html', and filled this term into the 'Package Generator'.
The zip-file that was sent to me only consisted of an empty folder ...

Please tell me ... What am I doing wrong?

Regards, Ben

p.s. my attempts are only locally available, so I cannot hand out a live URL yet.

The video under 'Documentation' => 'Getting Started' => 'Walkthrough Videos' entitled 'Package Generator' showed me enough to sort out my lack of insight.
It will probably take me more than 1 week (with ony 5 downloads with a maximum of 10 files per week) to pick up all the needed files for 1 template, but it gets me on the way.

Sorry for taking up space and time ...
Regards, Ben
