I have been working on a master's project in Word and have had various versions going; last night I made all my corrections on one version and saved it, then opened it this afternoon and finished everything and thought I had saved it again before emailing it to my prof, but the emailed version turns out to be from 2 days again and this is now the only version showing up on my computer! Even if I mistook and didn't save today, there should still be last night's version, but it's not there. I have already tried looking through all the other documents and autorecovery files (empty). Does anyone have any other ideas for recovering a document in this situation? If I could even recover last night's version it would save a lot of work.... Thanks!

You can take your system to a recovery expert (like Data Doctors, here in the Valley of The Sun). Just be sure you have your checkbook with you. Have you tried Googling for recovery software? Problem is, you don't want to disturb your hard-disk any more than necessary as anything that you change will potentially over-write the physical area of the hard drive that contains your deleted file images. Best of luck!
