Geocoding Ireland Address

Hi

Apologies for posting this here but I reckoned it was the most relevant place to post my question - given it's related to Irish addresses. I built a website for a client using Drupal 6 which is up and running. They now need to be able to add several Google maps showing their various locations. They also need to be able to update the maps themselves on a regular basis. I've installed GMap and Locations modules and got an API key and set it all up. I've turned on Ireland and UK in the Geocoding Options in the Location configuration.

When I create a new node and enter an Irish address in the Location fields, the address is not geocoded and no marker appears. If I use a UK address, the address is geocoded and the marker appears in the correct location. I am able to manually drop a marker on the Irish map which will do for the moment, but I will need the ability to geocode from the address. What am I missing?

P.S. Also, is it possible to have a link to 'Get Directions' in the pop-up info bubble when you click on a marker?
