Thx.
Got some answers. So my last question (3) where described in the faq, as these:
2.) What happens when my subscription ends?
You'll still be able to open your projects in the free edition, but you will not be able to edit or export them. You will still have access to all your files and assets.
This are heavy restrictions ! i have to say. I don´t like the idea, when your license ends, you paid a busines / personal license and after 12month you fall back to a free and even not able to edit something :-((
