Not to continue an old fight here, but I can see why people would continue to use JK2 1.02 rather than the updates, because the gameplay actually changed. But why would you use JKA 1.0 instead of 1.01? I mean, unless all your friends are using warez copies or something. :P
Granted, you wanted help, but I'm just saying. I don't see anything you're missing by using the old version here other than having only a few of the game servers show up in the browser (a bug in the first release).
