My project isn't opening in scrivener anymore...

I’ve been using Scrivener for the past few months without a problem. My project has saved automatically and it’s backed up every time i’ve closed it.
Today I opened Scrivener and the only thing that opened was the built in tutorial. When I look in the ‘recent projects’ tab, my current project is completely gone.

The actual project folder, stored on my desktop, is all there and up to date as far as I can tell. It just won’t open.
The only thing I can think of is that I changed the name of the project folder for arbitrary reasons. Would that have thrown off everything?

I’ve tried changing the folder name back to the original. Nothing.
I’ve tried importing the folder into a new project with no luck. It only opens sub-folders and sub docs which is useless.

Any help??
