It seems everything run well, but when I use Quickinstaller to install these 2 
products winthin a plone site, then I met a problem:
1. I coul add any events, but it couldn't show in Calendar, no link in the Calendar
2. when I creat a new plone site in ZMI, without to install the 2 products, 
the events' link to calendar works well. 

But I really need the function that these 2 products would provide, 
Pls help out.

My Env:

python 2.3.4 
Plone 2.0.4
