Ummm I need help

So I recently have bought myself a new graphics tablet, and it doesn't work.

First I tried plugging it in via USB and tried using a pen to write on it, but nothing worked

Then I realized that my brand spanking new tablet was now a smudgy with ink stains, so I tried to wash it off with hot water. Now when I try to plug it in, my computer doesn't reconize it.

Can somebody help me?

lmao u dont use real pens -_- and adding water to the mix is a no no i may think your screwed try going to there site and see if they have downloads
