The driver update from last week? That one didn't work. The one before that also didn't work. And the one before that either. If there's already a new one, I cannot download it right now, because the Wacom drivers pages just returns a server error. And don't even get me started on helpful the support team was... I won't buy any Wacom products in the future.
But I uninstalled the Wacom drivers before I bought Astropad last week. They shouldn't be related to this problem.
