Hello. After downloading, you should have received an e-mail from Arturia to activate the product. I downloaded but after 3 days still no e-mail and no way to log into my new account since I had not veen activated. This happened to more than a few users. I snuck in the back door by posting a message to their Sales Contact link stating my issue and asking them to forward my message to tech support. I got a Facebook freind request from Jason Valax from Arturia within an hour from Arturia explaining that they had activated the account for me. They had a huge amount of sign ups over the holidays. You might give that a shot.
