No matter what I do, I keep getting the index list when I access my home page (new site). How can I fix this? (http://gryphonskeypublishing.com/)

I have made certain that my home page is named Index.htm and that it is in the correct directory, but I keep getting the index list when I access my site.  I have two sites, and this new site (http://gryphonskeypublishing.com/) uses the exact same settings as my other site, which works perfectly.  Is it just because it's a new site, or is there a setting that I have wrong somewhere?  Please advise.  Thanks!
