Recover Files from dead link

Hello! 

I found some old Dropbox links, with files with emotional value, but since those links are from 2015/1016. I know the chances are very high the files are gone forever, but I still want to try to get them back. Can I maybe recover my old account and have a file uploading history or something? Can the Link help me with that? I also still have the email for that account, but I can't use it anymore.

(I have some more in case that helps)

I would have contacted the support per Email, but I could not figure out how to do so. 

Thank you all for the help already
