EUCON LICENCE * No Email Back after Registration

Hello my friends.
I’ve registered with 3 different emails on mysteinberg in the past 48 hours in order to be able to get a free licence on my eucon (2.7 or 2.6) to have it work on Nuendo 4, but got no registration account activation email… does anyone have any info about this…

I was there… and what I see is that I need a licence and for that, we need to register on mysteinberg… but unfortunately i«ts not possible since I’ve done it with three different emails!
Can you help me on this?
