All the files (especially ATL, just finished/had error previously) are up and working for X only at this point. Here are the latest links.
Make sure you are updated with latest patch
Just place the unzipped folder in your "saved games" folder, all the graphics and stuff should be there when you load it.
Make sure you dont unzip with an extra folder with same name, meaning click into the folder to make sure you dont have an extra folder level before you get to the main one.
Good Luck
