Brush problem... [PSP8]

Well, usually I can figure this out, and I have before, but I'm having a bit of a problem and I couldn't find this in the memories I've recently had to reboot my computer, and since it was just a system recovery my brushes were still in the file. But when I went to upload them to my program again, they wouldn't. I've tried relocating the brush file but that didnt work, and loading them as custom brushes.
