I bought, installed and run CTA standard. When I try to get into backstage I'm prompted to input my e-mail and pass to login, but log in fails every time saying serial number is not found.
When I go to my account I see the program is there. If I ask for the serial to be resend I'm prompted to log in but I'm already logged in. I cannot send a ticket for support when logged in because I'm asked to login, and so on.

What now?.
