My wacom pen does not work at all, the mouse on the tablet does though

That happens to mine too! I might contact wacom, because i spent £100 on this!

That happened to me yesterday. What I did was I went to the wacom site here: http://www.wacom.com/downloads/drivers.php, selected my tablet make and operating system, and downloaded the driver update. I installed it and as soon as it was done my pen started working again. Hopefully this works for you too!

Go to This website and post the same question http://forum.wacom.eu/viewtopic.php?f=9

exactly the same here

go to the pen tablet program folder and start up pen tablet properties and there should be an option to use the pen as a pen or as a mouse. if this does not help then the pen may have some problems.

I had the same problem and this is what I did
1) reinstalled the latest drivers from wacom.com
2) removed the tip (I pulled it out with tweezers) and put it back several times
3)went to the pen/tablet settings and restored everthing to defaults

Don't know which one did the trick, but my pen works again. Good luck.

Tablets are definatly more difficult to get used to! It will take some time before it's more beneficial to you. It doesn't appear that the tablet is at fault here though.
Be aware that the tablet's pen is pressure sensitive. Push lighter or harder in order to get more desired effects.

The winning answer came courtesy of Mr Benedikt Schmitt of Wacom Europe, who offered the following solution: from the Windows Device Manager, disable the “Wacom Virtual Hid Driver” device. (Go to Control Panel > System and Maintenance > Device Manager, find the driver, right-click it and choose “Disable”.) One reboot later (welcome to Windows-land, circa 2008?), everything works as desired. Pressure and tilt sensitivity inside Photoshop still work, and the pen functions just fine in the rest of the Windows desktop. The absolute mapping makes it an absolute pleasure to point quickly and precisely. It makes my laser mouse feel rather clumsy navigating a large 24′ screen!

I know this question was asked a long time ago, but I just had this similar problem and found a solution to it.

1. Install the latest Wacom drivers for your device
2. Open the Wacom Tablet Properties from the Start menu.
3. Click on the Mouse tool
4. Click on the Mapping tab halfway down the screen
5. Change the mode from Mouse to Pen
