Need some tech help re Microsoft Office

I'm using an older version of Microsoft Office and have never had a problem before. However, while I was trying to do something else I obviously screwed it up. Now, the default blank sheet (when you start a new document) has content from a prior document I sent some time ago. I've done everything I can think of to 'erase' it, delete it, whatever but it's still there. The worst part is if I go to print anything the first page that prints is the screwed=up default page.

Any suggestions as to how to clear my default blank page will be most gratefully received!!!!!!
