Couldn't Start Dropbox error message after updating the app

I keep getting this error when I try to open Dropbox after it updated. I have uninstalled and reinstalled several times. Removed the other devices using the app. I cannot figure out who to do this. The pop up says "Contact Dropbox support" but of course this company doesn't want to be helpful and supply support unless we pay a large amount. In all honesty I won't pay for a company that won't even allow some support. We are considering leaving Dropbox all together.
