Let me see if i can help you some here Alexo.
You ordered a full cd package. Not downloadable sets.
Thats why the link does not work and instead sends you to a 404 redirect.
It even states on the page you ordered from that full cd's are nor dowloadable. (see pasted copy)
""Full CD's are not downloadable. The download link after purchase is disabled. Default is delivery by mail, but if you want to have us upload to your server e-mail us
content@midnightdigital.com with the packages or cds you purchased along with your ftp info. """
We do have a service of uploading to you if you like.

Sorry for any confusion this may have caused you
