Just upgraded to FSX from FS9. Uploaded the NVG kit to it but come to press Shift F12 nothing happens. Could it be something to do with windows 7, as I've had dramas with other pieces of FSX due to Win 7. Also my keyboard button has a shared function for the F12 button, which is written in blue (corresponding with the 'Fn' button), however I've tried pressing Shift F12 with the Fn button applied and un applied, but this hasn't worked. Any Ideas?
