Unfortunately I don't know about CDO related stuff, so I can't answer that question.
Even after re-registering CDO, the error persist and is exactly the same.
(obs: The object created with CreateObj("CDO.Configuration") does point to CLID in registry, etc)

I would say that CDO.Message works fine, but CDO.Configuration is access denied by some unknown reason.
By the way, cdosys.dll has Apr/13/2008 as its version date tag.
