Hello,
I think I am having the same issue... I have created a document with multiple artboards. I have 24 artboards so far, and tried to add some more as I have previously.
When I select the artboard tool 'insert artboard' is greyed out. If I try to draw an artboard I get the message "Artboards cannot be added to a document with multiple pages or master pages" I have not to my knowledge done anything with "pages" and don't know how to do so, searching on the web seems to imply this is a function in publisher not designer?
Is there a workaround for this other than starting again from scratch - I don't really want to have to redo all the artboards I have already created :-(
Thanks!
