3D Camera Tracker Points Disappeared?

Hi there,

I've been learning how to use the 3D Camera Tracker in CS6 for compositing through a tutorial on Video CoPilot. I was making solids on the points and adding in new things when I suddenly lost all access to the the Camera Tracking points and I don't know why. I tried selecting the layer and the 3D Camera Track effect and it no longer makes the tracking points appear. I discarded the tracking information and re-analyzed and that made no difference. I don't know why it's not showing up.

Alternatively, I started a new project with the same footage and initiated the Track Camera command and it worked, the 3D camera points showed up. However, they still do not appear anymore in my main project.

Any idea why this might be happening?
