Naga Hex V1 side buttons not working

Hello,



I recently started to use my Naga Hex V1 again and I cannot get the 6 side buttons to work. I have tried what I saw on another post to reinstall the mouse, reinstall Synapse 2, clean sweep of all Razer software. I've tried different USB ports.



The mouse worked fine 1-2 years ago when I last used it.



Any help or suggestions would be greatful.



Thank you
