C&C renegade

The multiplayer for Renegade, which was hosted on Gamespy, has been shut down, sorry. 

There is a free fan game, Renegade X, which is quite similar to Renegade, if you're interested in that. 

XWIS still hosts Westwood Online, and it is active.  I have the same problem when launching multiplayer (after I select join on a server).
