NOTICE: No password is required for any downloads. Downloading sometimes fails, either because your browser mistakenly assumes a password is needed or for other reasons. If so, try using another browser or an FTP package. If that doesn't work, there might be a problem at your end or at your ISP, perhaps a firewall issue. Then you would need to talk to a system manager on your end..
