Project file could not be saved - Object reference...

Help! I see this issue has been discussed in the past but has there been any resolution? I have spent months on this course (it is 99.9% done) and now I cannot save it! The error reads: The Project file cannot be saved. Object reference not set to an instance of an object. I do not even know what this means! See attachment for the error message. Thank you.
