Can't Log Into Exchange Partner Portal

I am at my whit's end with Adobe. I contacted technical support for what is a clear technical issue with my account. I created an Exchange Partner Portal account yesterday. I have the welcome email, and have created a listing for a CEP Extension for Illustrator. My session timed out overnight and I tried to log in today but keep getting a "403 Not Authorized" error. The only thing that changed overnight is I changed the primary email address on my Adobe account. I have cleared cache, cleared saved passwords, etc, etc, etc. (I am a 20-year veteran web dev. I know the drill). No matter what I try, I get the same 403 error.

When I contacted Tech Support, they basically said nothing but "Please wait while I check your account" then sent me the same link I had been trying to log into and said, "Log in there. If it doesn't work, you have to ask in the forum".

How is someone in the Forum, with no access to my account going to help? I have no way to access my account. I can't create a new one because in order to do so you have to log in. Whenever I log in then try to access the Exchange portal, I get the 403. It's an endless loop.
