When I try to access them, the page opens, but when I click on an icon it opens with a 404 page error and a video with Lisa starts talking saying I need to be a full member.

All three of the new tabs do that. I emailed to let them know it was either my account or the site. It looks like it is site related if others are getting the same.

I'm sure once they find out it is happening to multipal people, they will get it fixed.
