Computer Crashed Now shows blank Doc

This has happened to me once before and it wasn’t a big deal because I had saved my files ahead of time.
I was writing and then my computer (a windows surface pro 8.1) crashed with the blue screen of death. Rebooted and went back into what I was writing and now that document is blank. However, there still says there are characters in the document, just no words. I tried opening the rtf file in both word pad and open office but to no avail.
Please help me! I was stupid in not making a screenshot. Also, how does ‘backup’ work with scrivener? I have it programed to back up everything when it opens and when I close out of the program. I see no benefit to this if I can’t go back with those back-up and restore my files!
