    Hi Christina, which nersion of V8 are you moving from?

    And did you have tabs and. /or groups organising your properties on your document types...

    ... The error message seems to indicate that a property group has already been added on a doc type with the same name as another...

    ... But that could be because of the reintroduction of tabs in V8...

    So you might need to upgrade to latest V8... If not check for any groups or tabs on doc types with the same name...

    Regards

    Marc
