usb e licenser

HI, I’m musicante from italy, I’m new, And I wish to greet all of you.
I have a problem: after dowloading the new e-licencer update, when I installed it, the sistem crashed. My pc is well working, and see the usb licenser. But I can’t install the software, and the key is blocked, the same for my cubase 10 pro.
I thought was a problem on the key, but I have another and is impossible also to charge the software.
My sistem is
windows 7
cubase 10 pro
usb e-licenser

Thank you all

Hi and welcome,

Have you installed eLCC 6.11 or 6.12, please?
