Look at the "SECURITY.txt" file in your ZOPE/doc folder.  There you can find instructions to solve your problem.

I have had to reinstall Plone and Zope on my computer.  I now find that when
I try to log into ZMI and http://localhost:8080/manage comes up, it tells me
that I am not authorised to view this resource.  I am using the correct user
  name and password.  I would be gratefu if anyone could suggest how to
resolve this problem.

Yours sincerely

Mark Smith
