USER and PASS: login Error 530

Can anybody give me a hand on this error? I was trying to log in to my server and it fails. It keep on giving the error message: login through USER and PASS? Error 530. I can't find this any where with my SmartFTP . Can the support guys give me a hand on.

error 530 is an ftp server error. it means (just google for it) "login failure". the reasons for this may vary (e.g. incorrect user name / password, denied IP, max. number of logins reached etc.). so the cause is your ftp server, not smartftp.
