Were you able to call support and get your FTP access resolved? If not, this article may help you with your FTP access and ability to connect with the server and see your files. From reading your previous post, we see there may be a few errors. You do not need the prefix/subdomain of "ftp." and take care that the user name and password is not the same as that used on the GoDaddy account itself. The article will advise you as to where to find these details.
