I am having a hard time making sense of what exactly you’re asking.
Since there is a robots.txt and some favicon files in your web root it appears that you’re able to login and upload files. No other files will be created for you by default, there will just be an empty directory for your domain.
Did you actually go into the admin panel and run a one-click install of a forum? If the one-click install failed but you’re uploading files and the url renders in a browser, only support will be able to help. If you haven’t actually kicked off the one-click install yet, then everything is working as expected.
As far as not being able to pull up ftp in IE or Firefox, it’s because you’re using the wrong syntax. Web browsers assume that you’re going to an http address unless you explicitly indicate it’s something different. Try logging in like this: ftp://username:email@example.com/
