eLicenser problem with Cubase 7 Elements

I have just activated my new Cubase Elements 7 with the activation code that I had received in the mail.
It worked fine, but then I upgraded my win8 to win 8.1, and now I can’t activate it again.
It tells that my computer’s soft licenser cannot be used.
What should I do?

Not sure if you can, but you may want to go back to Windows 8…
Have you seen this?

That’s bad, but my problem was with the eLicenser, not with the Cubase.

Don’t activate, re-authorize.

This might help.

I have downloaded a newer version of eLicenser and then the maintenance fixed it.
Thank you!
