Drawing tablet doesn't let me play Overwatch?

I am experiencing a problem on my pc for some reason. I have a drawing tablet I use and I think it might think is a third party device and it won’t let me play even though I plugged it out. If you had this problem before and fixed it, please tell me how to fix it.

You’ll likely have to remove the drivers for the tablet.

Is it a Hamachi Tablet? Those are known to me to cause problems if their drivers are installed.

Now if you are getting the error message when you log onto the game that says “We have detected the use of a third party application in violation of our EULA. Overwatch will now shut down.” that means you may still have either Pursuit or Visor, which were recently announced to be unauthorized by Blizzard.

Starting with this patch, the game will shut down if it detects the files of either application. Uninstall the application(s) in question and make sure you delete any residual files in your Program Files (x86) folder and your ProgramData folder (both located in the root directory of your C Drive).
