Updated version of previous post as the Review Title was too negative - that was the start - In the end I got it going.
WP Google Maps 5.14.
Installed plugin, it displayed settings, but wouldn't display the maps page (where I presume we would add a new map).
Deactivated - and activated - no go.
downloaded & installed, activated again.
Maps at page=wp-google-maps-menu - won't display.
Update WP from 3.4.2 to 3.5.2
YAH!!! finally displays maps page
Solution was to update WordPress in this installation.
(the installation was a test site - which was not updated to latest WP ver.)
Hope this might help someone else having trouble.
