pen no longer working with surface pro

Not sure why, but my pen no longer works with my pro. Tried restarting, but that didn't work. Any ideas how to fix? I have my power setting set for performance, btw. Thanks in advance.

Also tried recalibrating the pen. Can't because the tablet doesn't recognize it.

Maybe you can try rolling back the drivers or reinstalling the drivers.

Which Pro? Have you tried using another pen? I hate to suggest it, but it might be the digitizer.

The pen on the Pro 2, is a passive device whereas the digitizer ain't.
