If there is a download link on this page and you expect a torrent to be "well seeded" its VERY unlikely you will have much success - Our revenue funded Seedboxes usually only host for 90 days (more in some "collection" cases). Try requesting it on our forum, or, if available then downloading from another source (for example mega.nz, 1fichier or upto) - The best method of downloading would be .nzb (usenet) as most providers have at least 3 years retention - check out the "how to" on the NZB page - alternatively if you are a member there is a good chance it can be put on the members private FTP.
