I'm sure it has to be something simple.
What do you mean my username is different from my FTP username?

it means just as she said.

your ftp login username is different from your username login here with your bravenet account

so login to bravenet
click the ftp tab and make sure you get all the CORRECT ftp information there

so for example if your login with your bravenet account is sillyfred and your password is xxxxx then your ftp login is not going to be sillyfred

so get your ftp settings and punch them in with your dreamweaver ftp accouont area and then you should be able to upload your pages.
