Restart Nautilus-Instaling Dropbox

Question 1

I’m new with Ubuntu so I hope you can help me. I installed Dropbox using the terminal. Now when I open dropbox to try to log in this message apears:

restart nautilus

I do it but nothing happens. I tried this but nothing changed:

sudo add-apt-repository ppa:gnome3-team/gnome3-staging
sudo apt-get update
sudo apt-get install nautilus
sudo apt-get -f install

How can I proceed?

Question 2

Try nautilus -q or sudo nautilus -q. Logging out and back in should also restart nautilus.
