Which version of NPrinting are you using ?
Earlier than 220.127.116.11 used to get this message if there was a calculated condition in an object.
Just noticed the error message refers to a different qvw than is in your top image. Is that correct ?
I just gave the document name and try to save, and clicked on "creation an objest list.... -> YES).
Unable to find post a discussion link on vizubi forum, I can only find "Post a New Idea" link.
