Dropbox Backup won't restore or download and no option to copy Dropbox Backup to regular Dropbox

Hi Dropbox / Mark & Hannah,

Yes, I can attach photos I took of what occurred when I tried to Restore the backup, Download the backup, and also when I tried to download even one individual file.   And yes, I can attach them here... but if this forum is meant to be anonymous, I'll first need to take the time to color over / mark out my name showing on the various photos (the names of the backups, etc.)  And I can do that and post them here, but it'd probably make the most sense to go ahead and send me an email so I can respond to you / Dropbox and attach everything to the email without needing to scratch out my name on the photos.  

(Also keep in mind though, I copy and pasted the exact wording of each of the error messages, etc. into my initial post, so within the 1st post you have the exact information and wording as to what error occurred for each method / attempt to restore/download the backup (and also the attempt to download individual files, too).

Thanks!
