I purchased brushes from Heather the Painter in previous versions of Painter can I use those brushes in PE? I was able to bring the brushes forward within Painter but I am not sure about this program..
I only have PE4 which can't import brushes. I'm not familiar with PE6 as to weather it has an Import Brush or Category as Painter does.
However, since Corel sells brush packs for PE6 (which also seem to work in Painter, there should be a way to import Heather's brushes- you could always ask her on her website or Facebook page.
Note the frequently asked questions at the bottom of the page. Seems brush packs listed are for PE6 only.
