My pen has worked good till today. (H640P Inspiroy)
When I used it without the driver only a square area of the tablet would work, but with the driver active it would work good.
Today, when I activated the driver, the cursor didn't even show up.
I thought the solution was downloading the newest version of the driver, so I installed the version Driver_14.8.90, but nothing changed, not even when i changed the tip.
The lights of the tablet are on and work properly, the driver says "device connected", it's just the pen that doesn't work.
