photoshop elements 15 & hurion pen tablet

I've been using photoshop elements 15 for about 6 months now with no issues. the other day i went back to work on something and now it's not recognizing my tablet's pen.  when i press down to use the pen on my drawing i get a circle where i have to choose the brush stroke/eraser size. i do that but it still will do the same thing over and over again and won't let me erase or brush.  i can do it with my regular mouse so what gives? Hurion is saying it's an issue with Photoshop?
