Connection timed out... (I have searched first btw).

Hello all, Im fairly new to the using ftp clients and need your help. It seems it manages to connect to the ftp host ok but it times out when trying to login... this is what it says:

    SmartFTP v1.1.985.6



    Resolving host name waterman.siteburg.com...



    Connecting to (waterman.siteburg.com) ->  IP: 198.173.4.9 PORT: 80



    Connected to (waterman.siteburg.com) -> Time = 125ms



    Socket connected waiting for login sequence.



    Connection timeout. No response from server.



    Active Help Link: https://www.smartftp.com/support/kb/58



    Cannot login waiting to retry (20s)...

I haven't tried updating my firmware yet for my router (seems complicated - i'll leave it to ma dad), but I dont think its that. I've also set it to wait for 60secs just incase. Any ideas?

Any help appreciated,
Craig.
