Hmm, neither of those seemed to work.
Are you using Windows 7 ?
If you updated the WACOM drivers to 6.3.11 W3 you might have to go back to a previous version.
Go to http://www.wacom.com and go to Support then Drivers then look for link to Legacy Drivers.
I'm using 8.1, but ill try and see if its a problem with the drivers.
