Secondlina's Panels

I tried that :/ It didn't make a difference. I'm not sure what happened since the last time I used it and packed it back in its box *sigh* I've always been super careful with that kind of stuff. Is there a way to open it up? Like a battery or something? That was the only thing I thought it could be otherwise, but the instruction page I have only shows how to replace nibs and the side clicker. I've only used it 4 times, so I'm not exactly confident with it :/
