Could not connect to the database

jeg har script der har virket fint når vi køre med en lille tabel
CREATE TABLE `users` (
  `user_name` varchar(60) NOT NULL default '',
  `password` varchar(15) NOT NULL default '',
  `admin` int(1) NOT NULL default '0',
  PRIMARY KEY  (`user_name`),
  KEY `password` (`password`)
) TYPE=MyISAM;

men når vi ligge flere felter på så vil den lige pludselig ikke mere nogen der kan se årsagen..

CREATE TABLE `users2` (
  `aut` int(11) NOT NULL auto_increment,
  `user_name` varchar(15) NOT NULL default '',
  `password` varchar(15) NOT NULL default '',
  `email` varchar(60) NOT NULL default '',
  `adm` int(1) default '0',
  `fornavn` text,
  `efternavn` text NOT NULL,
  `adresse` text NOT NULL,
  `postnr` int(4) NOT NULL default '0',
  `bynavn` text NOT NULL,
  `baadnavn` text,
  `baadtype` text,
  `tekst` text,
  `pladsnr` int(6) default '0',
  `bronr` int(6) NOT NULL default '0',
  PRIMARY KEY  (`aut`),
  UNIQUE KEY `user_name` (`user_name`)
) TYPE=MyISAM AUTO_INCREMENT=57 ;
