Client close connection?

Hi - I just downloaded the latest version, having used Smart FTP for 4 years or more. Although it will connect to one server, it will no longer connect to the one I have been using before. All passwords and host words are correct. It just hangs at the Port and says Client closed connection? Here is the log

Solved it myself. Should have been Active, not Passive, even though it has always worked before on Passive.
