RenList Temporarily Down
Appearently renlist appears to be down the past 12 hours or so...
There are alternatives to join the server like RenIP: http://multiplayerforums.com/index.php?/files/file/640-renip/

Enter the path to where your game.exe is located, your username, servername, ip and port and click "Connect" at the bottom right.
Imperial Age Client
http://multiplayerforums.com/index.php?/files/category/82-command-conquer-renegade-imperial-age/
This client we assembled over the last few months for the server will join it without problems.
You do NOT need this if you have Renegade, however you may want to try it out anyway
It can run aside Renegade just fine and will not conflict with it.
Good luck & Have fun
