[Zope] CMF Collector

Hi all, We are trying to install CMF collecotr, but it is giving Error. The steps we followed to achieve this is as follows 1. Installed CMF 1.3 , Created CMF site -- Working well 2. Installed CMF COllector as a Separate Product, When we tried to create instance of collector it is giving error ID not found, after this not able to create CMF site also. 3. Un-installed CMF Collector, then CMF is working fine. Give the steps to be followed in installing the CMF Collector and how to configure that if any. thanks Srinath
