How do I use textured brushes as erasers???, on paint shop pro?! help :]]] Options

Well, i first save my "brush" and create it as a custom brush on my paint shop pro 9. BUT it will NOT transfer so i can use it!

example -->

that keeps popping up EVERY single time i try to transfer the brush! I tried many other brushes too and it keeps popping up that window >:/ I don't know why, am i doing something wrong?

i go up to file>import>custom brush
and i follow it along and than BAM! the window pops up RIGHT when i'm about to add it to use it as an eraser to get a grudge look on my work :/
