Help - connection trouble

Okay.. my friend set me up with some space on his server, but there's a problem when I try to connect..

Resolving host name ftp.ndorgs.com...
Connecting to (ftp.ndorgs.com).
No connection could be made because the target machine actively refused it.
Cannot login waiting to retry (5s)...


He doesn't know what's up. I'm kind of a n00b to this, so any help would be greatly appreciated.

Interesting: I was able to connect to the server without a problem, but, of course, not able to log in because of invalid credentials. Are you behind a firewall? Try using PASV mode. If that doesn't work, talk to your friend. It's probably a problem with the FTP server, not SmartFTP.

I just upgraded to most recent SmartFTP, and now can't connect, receiving this error message:

"No connection could be made because the target machine actively refused it. Connection closed."

I've uninstalled, reinstalled...tried to do all the right steps...still can't connect...bummer...don't know what I'm missing here...any help is greatly appreciated
