FileZilla FTP Server

The command line FTP ceinlt is hanging when I attempt to get a file or even ls a directory. I followed the steps above but it's still hanging. The Windows Security Alert dialog (on which the File Transfer Program could be unblocked') never appears. I've confirmed Display a notification' is enabled on all three profile tabs. Rebooting hasn't helped. It even hangs if I disable the Windows Firewall altogether! I'm stumped. Any ideas?
