[Zope] unable to use Zope PTK

[Rajil Saraswat]

hi,
this is a newbie trying to get zope PTK to work. I installed PTK on a win2k
system. The installation was fine, can see the portal in the available
objects lists. but when i use the object ortal, the wizard start up but when
i am completing it (after the login creation step)it gives the error
Error Type: AttributeError
Error Value: 'None' object has no attribute 'setMemberProperties'
what does it mean. any solutions. and why are there two products listed at
PTK page.
thanx
