Just an update..
I finally got the pen. It's working, but I can't do anything with it
The pen has the ability to move the cursor over the screen but only if i'm actually touching the pad or if it is literally 1 mm above the tablet. There is also no clicking/drawing.. So the full functionality of the pen is to move the cursor across the screen.
The funny thing is, windows keeps on installing a generic driver for the tablet. Even after disabling signature verification (just in case the driver is too old) it still goes and bloody installs its generic version. That might be the problem,I don't know. But I don't think I could fix it if I wanted to.
