I've been trying to get the downloadable levels for the original Splinter Cell, but I am not able to download them. In the in-game menu, I select "Download Levels". If I am already connected to Xbox live, it first tells me my controller is disconnected (even though it is not), and then asks me to sign in. If I am not already connected to Xbox live, it just asks me to sign in. After I sign in from within the game, it just tells me that it cannot connect to Xbox live, and wether I would like to start the network troubleshooter. If I run this, it just confirms what I already know; there is nothing wrong with my connection.
Is the DLC for Splinter Cell 1 still available? And if so -- any suggestions on how to get them?
