Lost binder file after attempting to sync with Dropbox

I downloaded the Scrivener for iPad and tried to sync a project through drop box on it the way the program instructed. It did not work. I deleted all apps and redownloaded and it still didn’t work. Now I’m trying to open this project on my mac where I’ve always used it and it says the IT COULD NOT BE FOUND and no binder.scrivproj file was located. I tried opening the project from both dropbox and my icloud, all versions are now corrupt.
I have no other backup and am panicking. Please tell me there is something I can do to retrieve the file.
