When your web hosting account is created, an FTP account is created for you automatically. The initial password for the FTP account is the same as your Control Panel password. If you opted to change your control panel password- this does not automatically change your FTP password. Likely, it is still the same as the original Control Panel password.
You will probably need to reset your FTP password.
