Hi
Zarukishimen, and welcome to The PainterFactory!
Since your problem is with both Core Painter X and Corel Painter Essentials 4, you might want to also post this message at Essentials Cafe which is the sister site to The PainterFactory, but it's for Painter Essentials.
You'll find a link to Essentials Cafe in the upper right corner of The PainterFactory Reception page.
Best wishes for getting the problem(s) solved.
Cheers!
