System specs are : Intel i7 950, Nvidia GTX285, Asus P6T Deluxe V2 Motherboard, 6GB Mushkin memory, 750 W power supply, 2 Raptor HD's, FSX on it's own drive (E), Doesnt matter which way I try to start vLSO, before FSX or after, says its connected on the vLSO UI, but on the task bar near the Microsoft flag, it changes from green to gray as I change from plane to plane, or date, or location, hope this helps.
