Problem w/ftp client

hi,

imi having a problem with my FTP client. it’s called smartFTP. when i use the domain [ftp.learningdesigns.biz(with](ftp://ftp.learningdesigns.biz(with) the correct login info) it logs in correctly but there are no files and folders to be found. it’s just empty.

someone i work with can login with an apple FTP client and they see all the folders they should.

anything to do with the port # or the .biz?
