You can try one of these. Unfortunately I haven't used either of them, so I can't help you with it.  Entering the information should be relatively the same though.

My only other suggestion is to contact whoever set up the FTP account for you and have them tell you what program they use.  It's possible that their server is finicky.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
