Just bought program. Starting a blog. How do I download

Just bought program. Starting a blog. How do I download to my Website? When I download it wants to go to my computer and then my computer can't read it. I want to produce a newsletter. I already did it in Microsoft Word newsletter template, but I can't cut and past that into my website page without losing all the formatting and pictures. How can I start over and create a newsletter here that will be a page on my website. Maybe I shouldn't put it as a page on my website and just use it as an e-mail? Opinion?
