Using CC FTP 5.2, suddenly getting message: "Internet connection has been dropped", followed by request to re-enter password. The Internet connection is functioning normally, I've made no changes to program, firewall has CC as exception. I've tried passive mode on and off. Another ftp program to the same sites works fine as always. Any ideas?

I would say since it's up to version 6.6 you should try upgrading and see if that fixes the problem.
