Well it's finally happened, and this is the first time it's actually happened like this. Usually my tablets die because of some hardware issue. But, this is the first time I've ever had to give up on one because it was so far out of date that my computer no longer recognizes the driver as a legitimate driver (The manufacturer hasn't updated the driver since 2009, so that should give you some clue.)
I figured this would happen sooner or later, as it was giving me some issues for a while now. Fortunately, I have a backup tablet, though it'll take some getting used to not drawing directly on the screen again.
I still have one commission to finish before I open up again! Well, start looking for commissions again...
