Hi,
Sorry for your situation.
Just to be sure: Are you posting a support ticket from your Arturia account while you are logged in, and do you get a confirmation on the website, when you submit it?
Also do you get a confirmation e-mail, that they have recieved your support request? You should.
Usually Arturia support respond within 24 hours, so i son't understand, why you don't hear from them. Which interest should they have in not replying?
Beside that, then have you tried to deactivate the product on your computer, then restart the computer and activate the product again after that?
This sometimes can solve activation/ registration issues.
I assume, you have checked, your OS is supported.
