YAMAHA XS7 + Cubase Essentials 5

Hello,
I read the materials available for software help, and Cubase Essentials 5 is not in the list.

But a simple question : Why my PC ask me for a key, when I connect my Keyboard to it.
Normally I didn’t need it before (a long time ago…)

Can you help me easily ?
Thanks ,
Enoch
