you probably need to enter your ftp information into the program.

log into your bravenet account, click on ftp tab, create an ftp account, get your ftp id and password.

take that info, open your editor program, go through the menu options to input that information.

The FTP address used for uploading isn't the same as the address that people use to browse to your site. That isn't a Bravenet thing, all hosting services are like that.

You can find all the required parameters by logging in to your account.
