Why do I only get a table of contents when I open Human Paleopathology?

In the search dialogue box:

• click on the Indexes button on the right
• click Add
• in the Object Name window, type k:\paleop.pdx
• click Open
• you should now see Human Paleopathology displaying in the Index Selection window, with a tick beside it; click OK
• the full product should now be able to be searched.
