Hey John,
Thanks for the email back! I found the original 4 autosave files through PowerPoint by clicking on File > Info > Manage Versions. They were originally there, and when I recovered the correct version, I tried to save it and the program crashed. When it recovered from the crash, it opened back up and had opened the very first version (which I had never recovered). All other existing versions (including the correct one I had tried to save) were not in Manage Versions anymore. Like I said, no big deal now that it is all taken care of, but trying to get a better understanding of this for the future.

Thanks!

Dan
