File Recovery of Accidentally Deleted Project

I had a power outtage while I was editing a project that I had been working on and was already saved before in my projects. When power came back and I entered into Rush the entrire project is now GONE. Not even the previous saved version is being shown. Is there any way to access the project files to restore my deleted project?? At least if I can restore from the last save point.... but there's nothing in the project window now. It's only the last project I was editing at the time. All the other projects are fine.
