I rebooted my system.  Logfile now shows a different error.  This error
is generated when attempting to connect via either psql or PGAdminIII.

MS firewall is OFF.
Un-installing and re-installing is fine.  But if there's anything that I
can provide prior to that for debugging, etc, I am willing to do so. (
If i can 'fix' it w/o re-installing it would be nice too ).
