The path name is case sensitive and has to begin with a slash. It may not be followed by spaces. If the path for example is /httpdocs/league, then there should be a folder httpdocs in the "root" of your FTP space, ie.e what you see after logging in with an FTP client.
But if the FTP client shows a message like "Opening directory /Users/Smith" when you're logging in, then you have to include that path, too (i.e. /Users/Smith/httpdocs/league).
If that doesn't help then please send me your FTP account info to
andreas.raht@sigames.com if possible.
