Keyfames not showing

I am using blender 2.49 and am doing the blender 3d noob to pro tutorial. I am working on a part that uses paths to move the camera and it is asking me to look at the keyframes, when I go into the SR:1 animation, there are no keyframes, even though I have checked “show keyframes” why is this and how can I fix it?

with your mouse in the 3D View, press K to see ghosts - outlines of the object’s position at each keyframe. With your mouse in the IPO window, press K to see keyframes - vertical yellow lines indicating a keyed position for the selected object at that frame.

Still not working, I would attach my blend, but it is to big, if you want to look at the tutorial I am using go here
