HELP! Cannot login error

I've tried logging to all ftp adresses I know, but I've always gotten this result:

Resolving host name ftp.smartftp.com...
Connecting to (ftp.smartftp.com) -> IP: 213.144.155.6 PORT: 21
Connected to (ftp.smartftp.com) -> Time = 0ms
Socket connected waiting for login sequence.
Cannot login waiting to retry (60s)...

It's not a problem with the username or the password, cuz I've tried every adress including ftp.smartftp.com which was in favourites. I've tried disabling my firewall with no result. I've also tried other ftp programs and now I'm out of ideas.

Is it possible that there is some setting in windows XP to blame?

Please help.
