WORD CANNOT RECOVER AN AUTOSAVE FILE.
 
Word cannot restore an autosave backup file.
Possible causes include:
 
■ A system failure occurred while the autosave
  feature was backing up files, and the files
  were damaged.
■ You saved files of your own using an autosave
  extension (.SVD, .SVS, or .SVG). Reserve these
  extensions for Word's use.
