Alright!
So everything is solved but I ll take the time to sort of quickly go through why I had this issue, just in case someone else bumps into the same situation:
First, the demo/released versions.
As stated above, they are the same so while you will find forum threads from 2 or 3 years ago saying there are several versions, as Rafa said, there aren’t!
The activation:
The main reason for which I had the issue to begin with was because the ‘‘Settings’’ button behaved… weird. To be more specific, when I would click it, it would open the help page corresponding to the ‘‘Settings’’ menu.
Weather it did open the menu somewhere or not… I m not sure… But I looked everywhere and changed all the layouts and I just couldn’t see it.
The solution:
The way I found it was by opening a project I had around on my computer, and then tried to press the button again.
This time a small bar poped open at the bottom of the 2Ds viewport (where your photos are displayed) that I could expand.
Here, you can find the above mentioned section for Licenses and ‘‘Change the application owner’’.
It will take you to a dialogue that asks you to login and then you will be able to chose your license from a pull down menu.
I hope this will help someone down the road but I decided to post the whole thing since on facebook there were several people also who mentioned they had simmilar issues.
Thank you for the help, Rafa!
