Google Maps 'API key' problem

I finally got this google maps page working however, it seems that everybody except the client can see it? They're saying the following error message appears "This web site needs a different Google Maps API key. A new key can be generated at..."

Here's the page: http://www.sportingemporium.com/google-map.htm

When I sign-up for a new key Goggle gives me exactly the same one that I am already using!

If anyone can shed any light on why I (and colleagues in 开发者_运维技巧many different countries) can see the map, but the client can't, it would be greatly appreiciated?

Kind regards, Declan Bradley

Check how they access your web site. The key is tied to a web site address. If instead of using www.sportingemporium.com or just sportingemporium.com they are using something like beta.sportingemporium.com, Google maps will complain.
