[Zope] still problems w/ SiteAccess 2.0.0b3

[Mario Olimpio de Menezes]

Hi,
	After struggling with Zope 2.2.1 + SiteAccess 2.0.0b3 upgraded
from Zope 2.1.6, I gave up: I purged the previous installation and
started from scratch.
	Now I have a strange scenario: SiteAccess is installed and I can
see SiteRoot and Set Access Rule in the popup menu but SiteAccess
doesn't appear in Products. So when I try to add a SiteRoot I get:

------------
Zope has encountered an error while publishing this resource. 

               Error Type: AttributeError
               Error Value: SiteAccess

	How to fix this? 
	I have restarted zope a number of times without success!
