CS6 is registered, shows in account, No Activations listed yet can't validate on new computer

I registered my CS6 in 2013. I have had several computers in that time. I just got a new one and when I try to validate the license, it tells me that I've already installed it on 2 computers. One of those computers died a sudden death and is long gone.

However, my account shows no activated devices so I can't even deactivate the old dead computer! I don't want to deactivate the license on the old computer that is still working (and that I'm posting this from). 

I noticed in a different post that you should not register within the product but go to a link provided. I went to the link on my new computer (I'm posting this from my old working computer - obviously not the old dead one.) But when I try to register on that one, it tells me that it's already registered. I have no idea where to go from here. I've been procrastinating asking for help and now it will be blocked on my new computer at midnight, I guess! And I have a deadline.

HELP!
