First of all, every time I enter an Arena or Offline Practice, an error message shows up saying "Invalid model Number." I'm not sure what that is for though, it just started showing up. If anyone knows what it is, that would help.
Anyways, whenever I join someone or someone joins me, there's a problem with shooting. For example, when I join someone and I go to a gunning position, I'm unable to shoot. It shows the ammo and stuff, but the gun doesn't fire. The same thing happened to the person who tried joining me. Does anyone know what the problem is?
Thanks for anyone that helps.
