So... I had a problem. I bought a H420 a long while ago, it has been working kind of okay so far. However just recently I made a mistake of downloading the wrong driver on another computer that I am going to use (not the one I'm using right now) and I only realize that when I plugged the tablet in. Now I am trying to use it on my PC but it wouldn't work. My question here is how can I fix my tablet? I went through the manual and I still haven't find anything yet.
