Error message "an error occured while receiving a reply line from the FTP server"


I'm running into a problem with my FTP service and am contacting all parties involved, including my ISP, FTP client software, 3rd party software utilizing FTP, and the owner of the FTP server.

I'm receiving the following error message whenever my 3rd party software attempts to log in to FTP through my FTP client: "an error occurred while receiving a reply line from the FTP server." It is then followed by a box that says "undefined error." The 3rd party software's technical support says it is a problem with the FTP client. My FTP server administrator says everything is fine from their end. I just purchased a brand new license for SmartFTP and am still receiving this error. What do I need to do?

Thank you

Nevermind, I figured it out.
