Can you show screenshots of your setup? Maybe you have excluded every object by accident, or something like that.

Thanks for the screenshot. I don't know what measurement units you are using and what is the scale of your scene, but it looks that you're using extremely large AO search distance. If your camera is in enclosed space and max distance is larger than boundaries of that space, then naturally your AO will come very dark, or completely black. Try to reduce max distance and see at what value you will start getting results that you are looking for.

Is the beauty pass and any other render element looking correctly for you? Is this only happening with the CTexmap element?
