Forum:Call of duty ghosts problem

I am very new to COD Ghosts and am only playing offline at present

I have come accross a problem during the game quite early on, where i get to a certain point  ( where the wolves attack ) and I am killed. the problem is that the game then goes into a loop playing the 'kill' over and over with the words LEFT MOUSE flashing on the screen. I have tried exiting and going back but it keeps going back to the same point. I have replayed the mission and it continues to happen at the same point. Can anyone help please ??
