How to restore files from Dropbox Backup

Those instructions did not work for me and presumably the same thing for @doesitwork. Let me provide more context on my usecase. I have a large usb stick that I do all of my work on and keep inserted in my computer. I set up Dropbox Backup to sync this stick to Dropbox in case anything happens to my physical usb stick. Something DID happen to my physical usb stick that rendered it unusable. I bought a new usb stick thinking I could just 1-click restore the data I've backed up onto this new stick. 

Instead, I receive no prompt from the desktop app to "restore from backup". Instead, I see an error message that "to restore sync, please re-insert the usb stick". There's no other options or prompts to restore. My only recourse is to "To only restore a part of your computer backup or any part of your external hard drive backup onto a new computer:" and select each folder I need to download. Of course, there's a limit on the number of files that can be zipped, so this is a very slow and manual process. In addition, there's no option for me to save the files directly to a location of my choice. They go directly to my Downloads folder so I then need to move them to the usb stick because my hard drive doesn't have the space for everything. 

Looking at this carbonite comparison https://experience.dropbox.com/resources/dropbox-backup-vs-carbonite, I don't see why I shouldn't use carbonite instead. Carbonite plus seems to do everything that I need and perhaps they've actually designed for this not uncommon scenario. It seems like @doesitwork has the exact same issue as me, but to a worse degree, considering they have 200gb of files.
