eLicencer problem

Maybe someone can help this newbie.
I bought a Steinberg UR22 which allows you download a free version of Cubase AI 8. So I downloaded the Cubase AI software and the eLicencer.
I used the access code as provided with my UR22, and Steinberg sent me promptly an activation code.
When trying to register the product with the activation code in the eLicencer, it is complaining that it can’t find the USB eLicence device (dongle). But I have a Soft license, so don’t need I dongle…
What is the solution or what have I done wrong…?
I’ve sent an email to the support Centre a week ago and still wait for response, so I get impatient so try over the forum.
