Hello there,
I use Samsung ATIV XE700T and Win 8.
It happens to me too after I uninstall the current Wacom driver (7.1.0-8 -Win8) and then install (7.0.9-5 -Win 7).
So why I installed Win 7 driver if I have Win 8 as OS?
Well, my stylus pen wasn't working on Adobe Flash Professional (was working anywhere else perfectly). So after I installed the Win 7 driver it started to work on Flash perfect too.
I am not sure if you already discovered but if you plug in any usb device, finger touch works for a while then again stops working. And the same thing happens when you plug out the device you plugged in.
As I am an illustrator, using pen on Flash for drawing is a priority for me so I didn't re-install the driver for Win8 again.
Solution:
1. Go to "Control Panel -> Programs" and uninstall the current driver (ISD Tablet).
2. Restart your computer.
3. Download and install this driver.
4. Restart your computer.
You are done!
