HELP! "The Project File could not be saved"

I'm working on a Win 7 machine and and working on rebuilding a project in Storyline that was originally done in presenter.   Everything was going fine until i started to load in the Quizzes.  Once i got to the 4 quiz, and i tried to save, the following error shows:

I have tried, save as, tried to save in a different spot.  This happened the first time i loaded this into Storyline and i now get an error that says the file wasn't created in storyline.  The file is saved in My Documents, not in a network drive. Any suggestions would be helpful. I'm afraid to close it, as to loose the work or even worse not be able to open again.
