Hi Mark,

 My pc is a windows7. After I posted I got to thinking and I may have figured out what caused the problem. The last time the weapons worked I was doing a multiplayer with my brother. I was firing shells and missiles and it worked fine but since then I have had this problem. Maybe the Capt Sim weapons don't like being used in the multiplayer mode.
 I am thinking I may have to an uninstall and do a reinstall. I wanted to get your train of thought first though.
  When I installed the weapons package I did "run as Administator" and it worked just fine before I used it in the multiplayer mode.       Dan
