I've been using Dropbox successfully for 10+ years. Last week I started getting an error message - see below. I double checked to see if documents created on my computer are syncing to Dropbox online and my phone. They are not. I have reviewed the help desk article and added dropbox.exe to my ESET virus protection software, but it didn't help. What to do? I'm nervous that my computer will crash adn I'll lose all recent documents as they won't be backed up in the cloud. There are a few red x's in File Explorer on some Dropbox files, but only a few. Lots of files have revolving arrows as if they are trying to sync.
