In looking at the map file, It seamed to me that you weren't zooming out to see the rest of the points that where plotted. sorry if I missed that. it may have helped if you noted the number of points you where seeing vs the number you where expecting.
When I view source of your page, I see that there are two record sets, the first returns 27 addresses, the second returns 12 addresses. then you have 1 hard coded address that I can see, Is that correct?
In the _promaps_geocache.xml file, I see 53 id's
try deleting that file to have it recreated.
Also, could you send a copy of yur google_javascript folder so I can investigate the map code.
