I think your video card driver is up to date
But this line in your last post suggests some sort of problem
The GPU Sniffer crashed on 5/29/2014 at 10:11:31 PM
Try changing your GPU Acceleration settings in Preferences. Click on the Advanced button, and change from 'Advanced' to basic. Or try turning it off completely.
I'm actually a bit lost as to the status of your problem and what you have tried.
Are you using the 32 or 64 bit version of Photoshop? (Help > About Photoshop)
Is the problem that the tablet is not being recognized at all?
Can you regroup, and say exactly where you are with your problem now?
