how i can see in the second picture, you had already registered your Cubase 6 version back in 2011. why you want to register it twice?

1.“Registration” and “activation” are two different things.
2.With a USB eLicenser you can´t (and don´t need to) reactivate the license. The way it looks from your screenshots though, it seems you have an empty USB eLicenser. You can not reactivate your Cubase 6 if it had been activated to a different USB eLicenser before.
