There are no files at all in your Automatic save file location of AutoCAD? If there is nothing I fear you have to start over again.

You've been drawing all day but you have not saved even once? Shame on you. The automatic save is not a replacement for manual saving.Read this: http://rkmcswain.blogspot.com/2005/07/autosave-mystery.html
