So I just got the 420 from amazon and Ive been pulling my hair out for the past 2 hours. I plugged it in thinking it would just start working but I saw I had to install drivers. I installed them from the CD but the tablet still wasnt picked up. I went to the website and downloaded the drivers off there and still it didnt work. I deleted the old ones everytime I reinstalled them and rebooted the computer every time. A program names "Graphics Tablet (64x)" would open up on my bar but nothing would show up on my screen. Id click it and then I would get that its not responding. I dont know if thats something important but I went along and rebooted anyways. I went into my programs and found Plaunch.exe but when I click it nothing happens. Another thing is the cable I got the tablet with doesnt do anything. I plug it in and the lights dont flash but when I use one I had laying around a green light starts to blink over and over again I dont know what that is.
