I have one that did the same, I sent Fiskers a email but never got a reply. It was useless as it was, so I jammed a piece of wood just above the red button, this could be dangerous as the cutter is always open, but as I never had young ones here, I don't have to worry to much, plus I keep it in a cutter Cady when not in use.
Hope you get better results with Tickets than I did
