530 Login authentication failed

I have two sites that are being hosted. My first one I am able to log into my FTP without any problems. I just got the information for my second one today, and when I try to log into that one, it said 530 Login authentication failed. I know I'm using the right login name and password, as I'm copying and pasting it from the email that sent me my information

Any help would be appreciated!

Please contact your web hosting provider for assistance. They can tell you why you are unable to login to their server.
