Have you tried unplugging the tablet and plug it back in another USB input instead? If it works you'll lose less time. Otherwise it indeed looks like you need a more recent driver. I have a very old Wacom tablet/pen a friend gave me and it's still functional. I'm not sure Wacom could get old enough to stop working properly, it's the best hardware of that kind and I'm pretty confident it's made to last. If it reassures you .
This happens to me fairly often as well... the driver just fails for some reason... I have since placed a shortcut to my tablet driver on my desktop and reinstalling it now just takes a few seconds. Annoying, I know, and I don't understand why it happens, but it does
same thing has happened to me, i found sometimes if my tablet was on my laptop keyboard it does it, im not sure if its something to do with the electricity (power) messing it up. kind of like how magnets make electronics play up. however i still sometimes plug it in and it wont work at all
