PSP 7 Help

I have PSP 7, and I had to recently remove it from my computer as I was having problems with it. I did not back up the brushes I had, because I needed to delete a majority of them anyway. I got PSP back on my computer, and went to 'create' custom brush as I had saved alot of them as jpgs as its easier to install then jbrs. Because they don't show up. Anyway, when I create a brush, its light. It does not look like the original image at all like it used to when I created brushes. 

Is there anyway that I can fix this?
