Are you firing the 120 ammo rockets? I had a problem with those. I just pressed Ctrl+8 a few to change the firing to 1+4 so it only fires 2 at a time instead of 60. I suppose, though, if you have bad luck with CS products, no sense in spending money on them, though I hope the seventy-some dollars you've spent on the two addons you have doesn't go to waste... keep trying! Sometimes things just start working, it's odd, and I wish it would happen more often...  ;)
