1) Don't post usernames and passwords
2) Change your password now
3) use your web browser to connect to mysql.bnote.org and type in your username and password. It should get you into your database. if not, then something's broken and you should contact Support.
If it does let you in, also contact Support, as it seems you've already double-checked your settings. It could be that the DB server isn't letting the Web server have access.
