Can I just set one directory for a Backup?

My Norton 360 (comcast version) Version: 4.2.0.12 , won't let me choose a single directory (folder) for backup.  Either by Including it in a bakup set or using windows explorer and choosing it from the Norton Security Suite menu item.

 

Also on the WHAT tab under Manage Backup sets, I don't have the Add a folder button which I have seen in another post.

 

Thoughts

Thanks
