I have installed the wilco citation x. I have both service packs one and two. I think the acceleration disk has both of them anyway. when I start the sim the panels are dark and none of the switches work. I have tried to change the security of FSX to allow me to do anything. Nothing seems to be working. This could really be a nice plane with a decent fmc if I can get the panels lit. Thanks for your help. I am using windows 7 64 bit. processor is 6 core amd and the graphic card is nvidia 680
