Help please with new (multiple) downloads

Hi all,
I have received a notification that I have to upgrade all my Steinberg products (or most of them) now the elicencer is being dumped.
I have been going around in circles trying to understand this. I am not even sure what I supposed to do and not do. Tried the FAQs. Anyway, I now have three products Dorico and DarkPlanet & Opus showing up as my licencer will expire tomorrow, even though I have owned them for years and they are on my dongle. When I try to go through the activation process I get an error message stating “No licence selectable” yet everything is working>
I really have no clue what is going on and fear that everything will be worse tomorrow.

Can anyone explain what is happening here please?
