Can't activate trial version cuebase 11

i am trying to activate my trial license through eLicense but it’s not working!
i am inserting my license code but i always get this message!

“Currently, there is no eLicenser connected to your computer which you can download your license
to. Please connect a … (something unreadable due to the cut in the message) USB eLicenser to your computer.”

I have done that virtually but nothing works !

it drives my crazy! what am i missing ?!
Very frustrating !

Welcome.

As the error message says, a USB elicenser is needed to try Cubase Pro.
