Problem in adding components to Concept HDL

Hi,

I was trying to do a Pspice simulation using Design Entry HDL, but I am not able to add components libraries. For eg: The tutorial says -

Select analog from the list of Available Libraries, and click Add. The analog library is added to the Project Libraries list. Similarly add Diode and  Source libraries.

I cannot find any of these libraries in the list of available libraries. Can anyone help me figuring out what's going wrong.

Thanks
