New machine, how to transfer soft eLicenser?

Both machines, old an new, are registered with Steinberg. Now I want to tranfer the license to my new machine, but I have no clue how to do that. The option to delete the license on the old machine is greyed out. When I re-enter the original activation code on the new machine then I get the message that the code is no good anymore. I don’t want to use any USB dongle on the new machine.

Worked like a charm, thank you.
