Looks like the dbversion table got modified but the dbupdate is not altering it. I renamed dbversion to dbversion.old and then created the new table and inserted the value and it now works.
CREATE TABLE `dbversion` (
`version_id` int(11) NOT NULL default '0'
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
new:
CREATE TABLE `dbversion` (
`version_id` int(11) NOT NULL default '0',
`lic_version` varchar(45) NOT NULL default '',
`lic_approved` varchar(45) NOT NULL default '',
`plex_id` varchar(70) NOT NULL default ''
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
