Ack, Edited the Wrong Saved Manuscript!

Okay, I need to start the day over already!!!

I think I'll slip into this picture and let it take me where it will...hmm-hm...

So what exactly happened? Not sure. I've done it before. Saved my current work-in progress on both my hard drive, external hard drive, and flash drive, to try and ensure I don't lose it. So the last place where it was saved was my flash drive. But when I opened it up to edit some more this morning--it had lost 4,000 words. Huh?

Thinking maybe I'd cut some more of the mss...
