Paint Shop Pro 8 Brush Trouble

So I recently got PSP8, and since everyone knows you can only do so much with the default brushes (in any art program), I downloaded some cool-looking brush sets from this site I go to for various resources. Unzippied them, put them in the brushes folder, fired up Paint Shop Pro and....Nothing. The brushes don't show up as selectable; it just shows the defualt brushes. And I tried using the Import Custom Brush feature, but it says that there's already a brush by the name of the one I'm trying to import. I'll see if I can post a screenshot or two in case my explanation isn't too clear, but has anyone else had this problem and got it fixed? Is there something I'm not doing (or not doing right)?

Try looking on www.about.com tell might tell you something and they also have pretty good tuts on how to cut and blend, use layers... All the basics you need for a good sig (if that's what your trying to make)Also i recomend you get PS, it's alot better

Maybe you are using an older version of psp? If not try re-installing the program or delete the brushes and find some that have worked for others or see if they are in the correct folder.
