Here's the error message. Note that the link:
dropbox.com/sh/rq1sol6gsa84iu0/zZLhEyob1f
opens the subfolder in a browser so I know it's valid.

I notice the error indicates trying to backup to... folder path plus the .capx name. The subfolder has nothing in it right now so don't know what's going on.
Any help would be greatly appreciated!
