I have recently noticed that there might be problems i the FTP servers gives a welcome message on more than one row. But I'm not sure...
How does your welcome message look like if you use an ordinary ftp client when you login to your ftp server?
Please check if you get any error messages in the console (use the console tab or start the console window: window -> console) when the ftp output runs.
This is the output text from ws_ftp, it is a typical FTP responce and may help you in debugging:-
