@Shawn and @sigross Thanks for the help. I got my sisters to help to check all of your suggestions. All systems were good. However, she discovered that my Cintiq wasn't being read or connected. Instead, it was working through a windows paint program. After realizing this, we figured out how to reconnect the Cintiq again. Then it said that the drivers needed to be updated.
So it's working better again. Hopefully, it stays that way. Thanks again, for jump-starting my troubleshooting.
