Story file from web published version

Hello Community,

I'm looking for a solution that I'm not certain actually exists.  I built a course in Storyline and published it for web delivery for course review.  After some changes to a process, it was determined that the finished course wouldn't be needed, so I didn't back it up anywhere.  My external hard drive died and with it, the original story file.

Now, a few months after abandoning the project, there's interest in resurrecting it.  Is there any way to get back to a story file from a web content file? My guess is that there is not, but before reinventing this particular wheel I thought I'd throw it out there to see if a guru could help.

Sceptical, but with hope...
