can you screenshot and post your render settings?
you have to make sure centileo is your renderer for render settings. Did you do that?

Your settings should look like this.
See where it says NodeSpace in the top right? That needs to say Centileo next to it.

My advice is to make a default scene for your c4d to load into every time you open a new scene. All you need to do is make centileo your renderer in settings, save the settings profile you want if you want as well (with default resolution and iterations and other settings you will use often), and save the scene to your c4d folder under the name "new" without the quotations. Then every time you open c4d new scenes will always be this saved scene.
And make sure cenitleo material and lighting icons are all saved to your custom palette layout for startup user profile.
