i had the sound problem, sent them a ticket.less then 24 hours i had a new install and now the sounds are fixed. i just can not get the missles to fire. when i switch to mis, it shows the ammo count but they wont shoot, either with the space and trigger. the guns and rockets work but not the missles. they did not work with the old installer also. they have great customer service and in time id bet they will get the bugs out of weapons. if i can not get the missles to work, no big deal, still have the guns and rockets to have fun with. thanks again      robert
