Huio Pen now working

Hello,

I have a Huion H320M with a PW100 pen (one of the models that is free of batteries). I use Windows 10. I've had my tablet for 2 years now, give or take, and yesterday, from one second to another while I was using the tablet normally as always, everything stopped working. After uninstalling the driver and updating it to the most recent one, the buttons seem to respond again but I still can't get the pen to work. It won't even sense it/hover on the screen.

Can you help me out?
