Meaning: Failed to mark the output as being updated. Marking the output as being updated, triggers other objects to be updated. If the other objects do not get updated, information about them could be incorrect. As an example: If the plate system's geometry could not be flagged as being updated, the plate system's parts would not have their geometry updated. Possibly cached memory has been overwritten.
Recovery: Reboot the computer to free up cache memory. If problem still exists, report steps that cause this error to your support group.
