Thank you for your support !
I do not have acces to this machine as i left my former job and didn't know i needed to do so.
I did use Guest Checkout and the licence key isn't activated on the adress wich i bought the product with.
I got a key on the check out email received on this very adresse . But no account and cannot linked the key to the account I created just now.
Can't believe this is not working.
Is it possible to send you this e-mail to prove my good will ?
