I am trying to install the downloadareav1.1 from mis. hacks
Small note/comment: don't use WS_ftp_LE if that's what you're using... LE is limited edition and its got so many limitations. Instead, I suggest try something like http://www.smartftp.com/ or http://www.cuteftp.com.
As to chmod, for most FTP clients you can just right click the folder you want to chmod, and then set to 777 (read, write, execute for user, group, and everyone).
