Problem uploading index.html file

Hi,

I am trying to upload an index.html file to my blog so that I could access it as http://www.marcus-baker.com/webinars.

I created the index file saving it as html in notepad. I am saving to to the web root (public_html/www) directory. The name of the file is correct. When I try to load it I get a message that the page cannot be found. Please help.

Thnaks
