If your account is linked to a NetApp system you should have access to download. If you have a guest account (i.e. not a NetApp customer and/or your account is not linked to a NetApp serial #) then you are not entitled to download the software. My suggestion is to open a support case as they can check entitlements or update your registration.
I know you contacted me offline, and we can continue the conversation there. Chris is right, if you do not have a support.netapp.com account (also known as a NOW account) then you will not be able to download the software.
