Help loading brushes please!

First off, let me tell you that I have looked through the memories, and haven't seen what I need. Here is the problem: I download the new abr brush set and put it in the correct folder (C:\Program Files\Adobe\Photoshop 7.0\Presets\Brushes). This much I have learned, but from what I can tell on all help sites and tutorials, this should be it. I should now have access to the new brushes when I open photoshop and use the brush pallet. However, they are not there. Can anyone help with this?

Also, I would like to say that you guys have awesome coloring tutorials, and I am so excited to have found you!
