Hi Henning @Henning
Good question, thanks for bringing this up!
You are of course entitled to the same benefits of a Studio License purchased by others but at a later date,
Please if you could write to lostfiles@laytheme.com with either you License key or the Invoice of Purchase, they will then be able to create a link for you to receive the Addon/addons that you are missing :)
Best wishes, let me know and have a wonderful day Henning
Richard
