For testing, please disable all security features of your firewall, so that all traffic goes through. Once this has been done, please retry connecting to that site. I can connect to your ftp server without any problems, using latest FlashFXP version.

If you can connect to your FTP server after turning off the firewall, remember to turn it back on immediately and search for a way to add FlashFXP as a trusted program. You might need to delete the FlashFXP entry in your firewall and re-add it completely. Also make sure that for some reason, there is no blocking of port 21.
I'm a bit wondering about the "Connection refused" message after only 0 seonds. Are you sure you haven't been using an FTP proxy or something like that before?
Good luck.
