Guys,
you are making a lot of confusion, there is no need to open a case, create an account, have access to the FTP servers and something else you are suggesting.
Elouerdighi, in the page you posted, you have to select just the language, then you will directed to the download page where you will find the products you are allowed to download, file by file, included SEP 11.0.4000.
Cheers,
