Hi David,
I logged in with my Adobe ID and was directly taken to a profile page "Your Account / Personal Information". On this page there was a banner "Claim your exclusive benefit today". By clicking the link I received the error:
Missing data: Unable to find a product registration record associated with your e-mail address (Adobe ID). If you feel this is incorrect, please contact Adobe customer support.
I had received similar offer already before so I was little supprised to receive it again.
Here is similar issues experienced by two users:
