If you have downloaded a script/mod and it seems not to work make sure you have followed the following 5 steps to happiness :-
1. Have you enabled the script editor by typing "Thereshallbewings" as your Pilot name? (Read The Activating The X3 Script Editor Stickie for more help)
2. Have you read the guides that are stickied on this forum
3. If the script is an AL Plugin have you saved your game after installing it and then reloaded to check if the AL Plugin settings are showing up?
