Roccat Kone XTD

Anyone got one of these? I've had mine coming up 4 years now and loved it but the left tilt middle mouse button has stopped working for some reason. All other buttons seem fine. Was just playing a game on HoTS and it stopped working. Anyone know anything I could try to fix it? Tried updating the driver but it uninstalled the config studio so I had to restore it back

Maybe hardware related. Does it actually mechanically 'click' at all, and feels OK? Do you have software that shows you all the mouse button activation besides the Roccat software (like for joysticks)? Writing a program to actually do that is trivial, but nayways...
