Rough Sketch brush changed from Painter Essentials 7 to 8

One of my favorite brushes in Painter Essentials 7 was the Rough Sketch. When I upgraded to Painter Essentials 8, the character of the brush changed .. it simply does not act like the old brush. Is there a way to move the files from (e.g. nib or xml) from 7 to 8 to get the old behavior back?
