Crystal report 2008 et base access 2007 (accdb)

Bonjour,
Je reprend une application exploitant une base de donnée Access 2007 (accdb) pour y ajouter une édition d'état Crystal report 2008.
Les états sont créer depuis VS2008. Connexion OLEDB ->Microsoft Office 12 Access Database Engine, toutes les tables de la base sont visible, pas de mot de passe.
Problème :
Impossible de connecter la base de donnée a l'execution.
Merci de votre aide.
