Hey @toddbosspoet, thanks for reaching out to us today!
This seems like the setup window for our backup feature.
With the Dropbox application, you can set your desktop folders to be moved and backed up to Dropbox, if you want.
It sounds like perhaps your Desktop and Documents folders are currently not in their default location, so the message indicates that they can't be backed up.
Do you want to back them up, though? If not, I'd suggest you just uncheck the folders or skip this step.
Let me know how it goes.
