Having trouble with brushes in PS7

I just got a copy of PS7 and I'm having a hard time with brushes. I've used PSP for years and that's so easy... but PS has me stumped. I've read the memories and I'm still having trouble.

I have several brushes I want to use, but I can't them to show up in PS. I tried the way it was suggested in the memories (click open instead of saving, extract files to Presets>brushes), and it wouldn't save them... just opened a new folder with the files there. I've tried downloading the zip files, extracting, then manually moving the .abr files to the brushes folder, but that doesn't work either.

Is there a step I'm overlooking? Is there another way? TIA!
