OK, so I was using the pen tool in photoshop just fine until it randomly stopped simulating pressure this afternoon. Not to mention the fact that when I restarted it, all my brushes were gone. What the heck happened, and does anyone know how to fix this?

I have the basic version of CS3, btw.

Never mind. I fixed the simulate pressure issue. I's still like to know why photoshop ate my brushes though . . . and if i can get them back.
