I want to stop using Norton Backup and remove any files that are saved there. I tried doing this through the nobu.backup.com website, which has the option to remove computers. On the homepage, all of my computers show up and I have the option to restore files. However, when I click on the "remove computer" link, none of my computers show up and all I have is an arrow that says "Done." How do I get my computers to show up so I can remove them?
