the most common mistake is putting your files in the wrong place.
Navigate to the "Manage Domains" page in the panel. Find the entry for dreamofsteel.com -- In the "web hosting" column it will say "Fully hosted" and give you a user name. This is the user you MUST be logging into ftp with. Once you log into that user, you will find a directory named dreamofsteel.com that was created for you, when you added hosting, switch into it and upload there.
