To download the zip you will have to have a login for the Downloads site. Without that, you will be able to see the zip file, but not select that for download. If needed, you can create an account by clicking the 'Sign In' Icon top right of the Downloads page and selecting to 'Create One'.
If you have an account, can login and are still unable to download for some reason, please Private Message me the email address of that logon account and I will try to check if you have access.
I did check your email account but that did not seem to resolve against a valid logon account, so if no account has been created yet, you will need to do that to allow download of that file.
If it has been created, then speak to Customer Care as Gurvinder says and get that corrected.
