Many services use the same SID and KID (you can get them with drmdbg, drm2wmv included into Automate unDRM) for the same media file. In case of such a service you may get a license (actually SID and KID values) from another user.
You may try p2p networks (BitTorrent, eDonkey2000,...), forums or whatever other means.
Please don't ask about it on this forum, 'coz your post will be deleted than.
