I Just purchased this mouse and I have the correct software downloaded to be able to re-keybind the side. Plate of 12 buttons.. I go to the mouse binding option and the little screen pops up and its not letting me change the key bind at all.. I have spent the past 2 hours looking things up on google to hopefully find a solution and I am not getting anywhere.. Can anyone help?

I would like to remove the default keybinds so I can get different hot keys rather than ones I already have in use
