Help! Upgraded Smart FTP and now can't log in to my sites

After the upgrade, some sites log in as before and others just hang and don't log in. Any ideas?

Don't mean to butt in but I don't find any place where I can address problems. I am not techno educated enough to get techno talk from tutorials. Is there someone who can answer my questions by emailing me at

cookie.parker@yahoo.com?

Thanks.
