FTP can work in 2 ways - active and passive. In active mode, it requires
your firewall to allow an incoming connection back for data transfer to a
port defined by your FTP program (it will send a port number to the server
to tell it to connect back). Passive mode tells the server to return a 2nd
port number for the data connection, and then your FTP program will make a
2nd connection to that port.
It sounds like you're trying to use active mode (it might be the default
setting in that FTP client) and so the 2nd connection is being blocked as it
won't allow the server to connect back. Either add an exclusion to the XP
firewall for your FTP client (this should allow connections to come back to
it), or switch the setting to passive mode in the FTP client (this is the
better choice if the FTP server works in passive mode).
