connection problems

i dont know if this was addressed earlier, but sorry if it was, i'm tired and annoyed coz i cant connect to ftp. havent been able to all day...

this is the error msg i get repeatedly:
Resolving host name shisou.net...
Connecting to (shisou.net) -> IP: 66.227.50.236 PORT: 21
No connection could be made because the target machine actively refused it.
Cannot login waiting to retry (30s)...


what do i do to resolve this? it does it to any domain i try to connect to, until today my ftp was working fine... and now suddenly this...

anyone? please?

Have you instaled a firewall? if yes try to disable it and check again, some firewalls don't works ok with SmartFTP.
