I didn't have any luck trying to open your file. It looks to me like it is too far gone for recovery.

I tried Zoho Writer, Word's Open and Recover, Notepad++, Wordpad and 7-Zip. Wordpad did open the stream but there was nothing recognisable in it apart from the listing of graphics which must have been in the file.
