Oh no, Denise, I'm sorry to hear you're facing this.
There isn't a way to download a source file from Review 360. Can you still access the hard drive? If so, it may help to see if the .story file is in your temp files:
- Open this folder in Windows Explorer: %appdata%\Articulate\Storyline
- Scan the contents of this folder for a file that starts with the name of the project. If you find one, copy it to your desktop. If you find more than one, copy the latest version to your desktop.
- Change the file extension of the copy on your desktop from *.tmp to *.story.
- Double-click the file to open it in Storyline.
