Storyline not saving TMP files

I'm having the same issue as Sushil. Was a solution ever found on this? I've been working on a file for about two weeks. It's been saved multiple times every day during that time. There are no temp files of the project in my AppData\Roaming\Articulate\Storyline folder.

It's very important that I'm able to recover an earlier version of this file. It's also been published to Review, and that version contains some needed information that was accidentally removed. I know that it can't be recovered from there, but I'm hoping there's a way to find at least one temp file.
