Master list server for enemy territory is down since some weeks, and don't it knows if it is a bug that will be solved by ID or if it is a decision of the company. To fix this problem, the Trackbase community did create an alternative solution, that consists in an alternative master server and new modified executables that are pointed to this new maaster server to get a server list. The solution is posted in the site
http://etmaster.net/, and it is a simple way to fix this problem. I hope that it can help the people that are still playing TCE.
