I just purchased the Weapons for FSX today and have run into some difficulty. I am running FSX SP2 and the game seems to crash every so often -  a heck of allot more than before (like 6 times in just 3 hours), Also, I can fire and launch the weapons, when it hits the ground I see the effect but if I shoot an airplane the airplane just drops down to the ground/water and stays there.....no explosions or fire.....or even smoke. :-?
