I uninstalled/ reinstalled the Cd program that came with it a few times as well as updated the driver:


I Run windows 7, and I wanted to come here before contacting the company just in case there's something I could of overlooked. I've had this tablet for a couple years and it worked fine until recently. It started jumping randomly i'll go in a straight line and it will flicker to random locations off of the line, it's 11.5x 8 inches and i'll start from the top right corner going across and by the time I get half way sometimes it's a good couple inches behind or ahead from where it should be. Nothing has changed as far as I know and I changed the battery in the pen as well, any ideas?
