If you mean you experience the ConsoleOne lockup when adding your user object to the Formativ Administrator object, then I suspect you may have an issue with your installation of eDirectory and/or ConsoleOne. Performing this action does not use any Formativ Snapins or eDirectory objects. (Both the user object and the FormativAdministrator role objects are native eDirectory objects, and are not touched in any way by the Formativ ConsoleOne snapins).
You may want to try deleting your Formativ Administrator role object, then re-create it and try again.
I hope this helps.
