Nothing happens when I use my middle mouse button (Mouse 3). I tried rebinding it, and it's already middle mouse button. I change middle mouse to "2" and it works only sometimes, but pressing 2 on the keyboard works everytime. I know it is being pressed correctly as I switched the vibration on click on. Model is Steel Series 500. Have been playing for years and never had this problem. Have been away recently and now it's not working. Also in game only shows the prompt to press 2 to use gadget, not anything else, even though both 2 and middle mouse are bound in the controls menu.
