I can log into my account and upload files both on the net2ftp and on my own ftp program. But when I try to view my page i get an 404 error. In net2ftp I can "view" or "edit" my file correctly, but when I try to "open" a file, I get the 404 error. Is there a setting I have forgotten or something?

Did you by any chance sign up with capital letters in your username and ignore the rules on the side of the sign up page?
