I dont know what is wrong

Ok, I have a major problem. I cant shoot pistols, use 3 burst, slash in wolf form, or regular slash with a knife. My mouse is new. I plugged in my old mouse to see if it would work, but I came up with the same results. I cant shoot automatic weapons cause I just hold down the left mouse button. I can use heavy slash with wolf and heavy slash with knife, and I can go into three burst mode and zoom mode.
