If you are already using the esn feature, and dont have the disc, you have 2 options. 1) If you know the what the title of the cd is, buy a new copy of the disc (all cd's are stamped from a master and are identical), make sure its the same cd, and not a different version or remake. 2) If you dont know what the cd is, you have to call Eclipse customer service. Good luck!
