WS-FTP Pro suddenly stopped working

Apologies if this is NOT -- I'm posting here because I suspect
there's some setting I need to change in Windows, though I don't know
what.

Yes, I did email the software makers, following instructions in the
help file, but I didn't get a reply.

I've been using WS-FTP Pro for years without a problem, but suddenly
on Friday I stopped being able to connect to the same sites I'd been
connecting to for years. The two are completely unconnected, so I
don't think it's a site problem.

Specifically, WS-FTP Pro goes through the connection protocol and
logs me in with user name and password to either site, then changes
directory to my specified starting directory. So there is some
communication. But then it hangs trying to get the file list from the
remote site, and eventually times out with "retrieve of folder
listing failed".

When I use Win XP's command-line ftp program, I can do an "ls" and
successfully get the remote file listing. I can also upload files,
and verify in my Web browser that the uploads were successful. So
there's something in the particular protocol that WS-FTP is using to
get the remote file listing that is now being blocked by my computer.

Initially I thought this was a change that my cable company
(Roadrunner / Time Warner Cable) had made. I'm suspicious of them, of
course, because they dropped Usenet and gave a mendacious
explanation. But yesterday I took my computer to work and to the
college where I teach, and through their networks I got the same
problem. That's not 100% conclusive, because they might well be
connecting through RR as well, but at least it says there's not a
problem with my cable modem in particular.

I've got XP/SP2, WS-FTP Pro 6.05. Any ideas?

Wait for the software maker's answer.
