When you don't specify the remote FTP directory, the "/" root directory is taken as default. As I don't have root on that server I am not likely to have access to that directory. If a default directory accessible to that given username can be opened, it will solve the problem IMO.
Can you post a log file?
P.S. I don't know the mechanics, but to me it seems that the server sends a response to the client, where it informs about default directory. I think this is quite easy to fix.
The mechanics is that the server sets current user directory to default directory (home directory) and client asks the server for path to current local directory (PWD command) to display the information to user.
