Particle system in blender 2.46

I wanted to check out the particle system in blender 2.46. But everytime I hit the button “set editable” an error message appears “particle system not enable, skipping set editable”.
Also after addiong a new particle, my object does not appear in the rendered window, I just get the background
What is happening?

Have tried pressing ALT-A or play in the timeline?

You can edit only hair particles for now I think …
