File>Open Recent Files> File does not exist.

My file seems to have vanished from the face of the earth. I created this file a couple days ago and worked on it again yesterday morning so I know it does exist. When I open Illustrator the file doesn't show on the home screen at all so I go to file > open recent files and click on my file. I comes up with the error file does not exist. I've done a search through my whole computer and it's no where to be found. I'm thinking it's just gone forever and I'm going to have to restart but I figured I'd ask for help first. Any suggestions would be much appreciated, thanks!
