well with you saying you deleted your index.html page from the directory that is why you have the page that comes up now
YOur main home page to your site HAS to be index.htm or index.html
when you sign up for the free hosted subdomain or purchase a domain you have a placeholder index.html page already there. ALL YOU have to do is make your index.html page and publish it over it
do not mess with what bravenet puts in there then you have a mess as you may have at moment
so whatever your homepage is just change the name to index.html and publish it to your root directory
then you can do whatever you want with rest of your pages basically
