If this occurs on startup of the developer, it can be due to a corrupt point definition. Usually, editing the Point and pressing OK is enough to correct the corruption. If there are too many points, select a large group and use the ‘Multiple Edit’ function to assign some common attribute to them all e.g. OLE Access is Read Only. This in effect edits each point, also correcting the corruption.

If this error occurs in the Runtime it means the point has been deleted or renamed but a script or animation is still using the Point. Run the Analyse Application tool to highlight and fix References to non-existent points.
