Start Menu / Folder Options: Nothing In The Left-hand Column?

When I open up the Start Menu on one of the accounts, there is nothing in the left-hand column. When I right click and get the Properties, and try to Customize the Menu, the options don't save, and I'm stuck with nothing. I've tried clicking on the Internet radio button for "Show on Start Menu". I click Ok, then Apply, and Finally Ok again. But when I go back to the menu, it still has nothing in the left-hand column.

The second thing I've noticed was under Folder Options -> View, I tried to check both the "Show Hidden Files and Folders" button, and also un-check "Hide extensions for Known File Types" and click on Apply, then Ok again. But still, these options don't save and are reset back to "Do not show hidden files", and "hide extensions".
