Can't open recovered Document

I modified one saved file (in its early stages) so I could use the format of the existing chapters and scenes, and a lot of notes I have in the Project Section. I renamed it, of course. After working for about fifteen minutes labeling scenes with quick notes of what they’re about, getting about 20 of them down quickly, I hit Save As…The notation showed that I was unable to save and it was saved as a recovered file. However, when I tried to open the recovered file, the underlying sections don’t highlight to be opened, and I cannot access those files (or the main file.) I can easily redo the 20 minutes work, but I am afraid that after I work for an hour or two, the same problem could reoccur, causing me to lose all of that work. Do you know why it is failing to save, and goes to a recovered file, which I then can’t open? Or can you help me open the recovered file?

No longer need help here…AmberV helped elsewhere…
