|Yes, I originally thought you might have just changed its extension from dbx to doc.|
It now looks like you are not set to show known file extensions and that you saved it as a doc. That is why it now appears as "Daily Guru.doc.dbx". As StuartS says, it is therefore beyond recovery. Pity you didn't just keep it as a dbx file.
You could peer inside it with a text editor but I doubt there would be anything readable.
Please come back and let us know how you got on.
