If you have repeatedly tried to login to FTP with the wrong details then your broadband ip address may be blocked by the server. Contact your hosting company to find out.
What FTP programme are you using to try and connect? I recommend either FileZilla (free), the Fire FTP plug-in for the Firefox browser (free), or WS FTP Home (30 day free trial).
