No notes

Hi, I believe I set all the permissions correctly but I just get an empty meta box that says no notes on the page and posts admin page… I do not get anything that looks like your screenshots: http://www.theblog.ca/wordpress-post-notes

Also when I set permissions on the set up page it has added a zero which is seems to default to immediately after clicking save? Thanks
