Disable access code?

Hi all, 

I know this question has been asked before, but I'm at a loss so I'm putting it out here anyway. I know the password to my account, but I no longer have access to the email associated with it. This wasn't an issue until the passcode was required, not too long ago. I'm really hoping there is a way to have that temporarily disabled so I can log-in and change my email. From what others have stated, it sounds like this may not be possible, which baffles me. I have years of really important data stored in Dropbox. It seems like there has to be a better way, Dropbox. 

 

Any help would be appreciated.
