Couldn't Start Dropbox error message after updating the app

[GargoyleAnt]

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.

Hey @GargoyleAnt, thanks for bringing this to our attention and sorry to see you're having trouble.

Can you try a more advanced reinstall of the Dropbox application, to see if that helps?

Let me know and we'll go from there.

[GargoyleAnt]

Yes it didn't work either.

Hi @GargoyleAnt, I just sent you an email!

I'll be more than happy to continue troubleshooting with you there. Cheers!
