Adobe Premiere Pro Certification Renewal

Hi.  Adobe Support recommended that I post my question here.

I have several Adobe certifications - including one for Adobe Premiere Pro - that I am seeking to renew before they expire. The Adobe account under which I had earned them was associated with a student email account that has since been shut down and rendered inaccessible. That means I can't access that account, log in to use the Adobe online tool to update my email, or use the reset my password function (which would require retrieving a code sent to the old address).

I opened a case with Adobe's certification department about this issue and they directed me to Certiport, the third-party service through which I earned the certificates. Certiport has updated information on their end but said I need to go through Adobe to get my email address updated for my Adobe account.

I've spoken a couple of times with Adobe Support, who pointed me to my school district's IT department.  The IT deparment said the email address is inactive and cannot be re-activated, and said I would need to speak with Adobe.

Which brings me here.  Can someone offer me a way to either access that old account or to have the certifications associated with my new account that actually has a valid email address?  

Thank you for any help you can provide.
