[Zope] Can't establish connection to localhost

[Carl Symons]

Been working with Zope error-free on localhost for months.

I just tried to install a plone skin, which I've done successfully previously.

Directions are to restart zope

Attempting to do so returns message:
Unable to connect
firefox can't establish a connection to the server at localhost:8081

Rebooted...same symptom.

What should I do to get Zope running again?

Linux
Zope 2.8
