Gd[d] has no properties + GMap is not defined errors

Hi.

Ive just downloaded the basic sample startup code from google after
getting my reg key. Tried using it and it doesnt work on any browser
(Firefox / IE6) . I get these error all the time originating from the
imported google script

1. Gd[d] has no properties
2. GMap is not defined

Is there something i should know ? I would have expected a simple
startup script to work. Has anyone else had this problem ?
