Nice mod!!! There were some small errors in the scripts: TABLE_PREFIX was missing for some WHERE statements in the php file.
Also I've took out the ENGINE=MyISAM database bit to ensure the devnavbar_navbar table is created for versions of mySQL not supporting this type of databases.
Also I've changed the script a little bit to group multiple nav bars in one table (instead of having each bar in a seperate table) and to spread the columns evenly using the width attribute. Have a look if you want to revert this in your official download...
