Trying to register a license via the VAX menu and clicking on "Create account" in the registration window opens a 404 error page in the web browser (https://license.codegear.com/srs6/customerNew.do).
That makes it impossible right now to register a new key to your product.
Also going to https://www.codegear.com/ directly shows a big warning in Firefox because the site's certificate seems to be invalid.
I'm sorry for the inconvenience. The web team is working on a fix. In the meantime, if you are blocked from using VA, request a trial license extension by sending mail to [email protected].
