Installation Joosurvey sur Joomla!1.5.X

Bonjour,
voilà je viens d'installer Joomla! sur mon serveur. J'ai par la suite installer CommunityBuilder pour pouvoir installer Joosurvey.
Une fois Joosurvey installé je vais dans la gestion des composants, et là quand je clique sur Joosurvey>Préférences j'arrive donc sur la page des Préférences, mais j'ai deux erreurs mysql :

-Warning: mysql_fetch_row(): supplied argument is not a valid MySQL result resource in /airbus/components/com_survey/common.php on line 704

-Warning: mysql_fetch_row(): supplied argument is not a valid MySQL result resource in /airbus/components/com_survey/common.php on line 647

et au milieur j'ai une fenetre avec un erreur : Erreur
Il semble que quelques tables ou champs soient absents de votre base de données.

dessous j'ai un bouton pour verifier les tables et les champs, quand je clique dessus le test s'effectue et j'ai cette réponse :
