I have just recently installed a Wacom Intuos 3 on

I have just recently installed a Wacom Intuos 3 on my Hp pavillion dv7. I have Windows Vista Home Premium edition. So, it turned on my tablet PC option. Now I have a tablet PC input panel on my screen that was working just fine up until today. I have been using it for a couple of weeks now with no problems at all. Now it will not let me write in my own handwriting. When I try to personalize handwriting recognition I receive this message. Ink is not working on your computer right now. It tells me to restart my computer. Which I have done several times with no luck. Someone please help!!! I have even uninstalled and reinstalled my Wacom tablet to try to correct the problem. This didn't work either. Can anyone help????
