Problem - can't save revisions to show

Multiple attempts to revise my embedded show have failed today!

I've made revisions to my show, seen that these revisions were saved in the upper right corner of the show display, but have not seen revisions displayed in my embedded show.

I cannot save the show in the File menu, only Save As. When I access the show from Open Recent, I go back to an early revision.

I am giving up! I hope this is a temporary glitch, and will try tomorrow to make revisions to my show. If this problem continues, please advise - Why can't I save changes to my show?
