surface pen driver

[Tipton]

My surface pro 4 pen is not drawing. This has happened before. I've taken out the batteries, unpaired it from my tablet, updated my tablet, turned off my tablet, and still only the button works. The drawing part only worked once i sent the pen in to microsoft and got a new one. On top of that, I bought a backup pen. Now neither of them are working (except the buttons). I don't want to go through the hassle again. Is there a driver I can download that fix whatever bug I have going on with my pen not working?
