Can't access account under deleted email

That's a shame. The email is long since deleted, but I can still sign into the dropbox account... I'm just not able to actually get true access since it says "please change your password, we expired your password as a security precaution"...

 I am not signed into any devices. I tried going through one of the automated services you guys have where you guess what the name of a folder is on the account, as well as my name and city last signed in from, but to no avail. Is there really nothing else that can be done? Like I said, I can sign in; I have the email and the password, and I can prove I am the owner, it's just that I can't access the long deleted email the account is assigned to..

Thanks,
