Painter Essentials 6 not drawing

So I recently received an Xp-Pen Tablet and the Painter Essentials 6 software for my birthday. The program itself works and my tablet too but, after I chose a brush it doesn't draw and I've tried selecting different brushes and even buying a new set. This still didn't change anything so I just need to know if there's something I did wrong during the setup or why I can't draw even though everything works?
