Connection Problem

Hello.

I can never connect to my site(s) with FTP. I'm sure I've put in the right address, username and password, coz I tried it a MILLION times. It can't really be the server being down, because I tried connecting to a number of different sites. This is what I get when trying to connect:

I went to the link, but it didn't really help me much coz I didn't really understand the solutions listed.

Help would be much appreciated.
