At the start of a campaign, after loading a saved game and every ten turns if the script is not activated there should be a sound coming out of your speakers warning you about the script.

Or even batter. Make sure a horror movie monster blinks really fast on the screen, with appropriate sounds and growls and everything that comes along and then display in bloody letters that you must activate the script (idea taken from some else, they know who they are).

Really, this is nice what the EB is going to do, but for the love of God! It's like written in large bold letter somewhere that you should activate the script!
