Replacement dongle can not be activated

I got a replacement dongle because the old one was lost. With the Lizenziate, which is present in my account, I can not unlock the new Dongle, since it belongs to the old Dongle. Of course I tried this. I am always rejected with the error message wrong licensors. Get license does not work, because I did not receive any code. Overwriting the licensee is also not possible. What can I do?
