in the map js file, try removing the code that loads the directions:
directions = new GDirections(map, document.getElementById('wagmp_directions_12'));
GEvent.addListener(directions, "error", function() {
map.setCenter(wagmp_map_12_obj.points[0], 13);
map.addOverlay(wagmp_map_12_obj.markers[0]);
});
directions.load('from: ' + fromAddress.full + ' to: ' + address_0_0.full);
wagmp_map_12_obj.directions = directions;
