This happens once a day. It'll start blinking, and the pen won't work. I'm pretty sure that the program is updated. Do I just need to replace the pen nib?
Do you mean a part on the pad itself, or on the pen? If its the former, then mine does this often enough. I just have to restart my computer and it'll work just fine. I'm not sure what causes this, or if I should even be worried. I just know a quick reboot will solve it.
