If you saved the file (past file saved/doc.) your wizard will find it. If your wizard cannot locate it Then:
Open your MS Word file and read what you have stored and the time & date it was stored; or click on thumbnails and right click to open your files. You may have to do this manually if your wizard does not locate it.
If the "pop-up" deleted your file,..... maybe go to system restore OR check your trash bin/recycle and see if it's there.
