gmap won't geocode?

I was working with the gmap macro creator and for a particular address I have, it won't geocode. I'm having the same issue with Location also where it won't find the lat/long for the address information I type in. I type the same address in Google Maps, and it shows me on the map just fine.

Could this just be that I'm using the wrong API version? Or is it something else?

If anyone else wants to check this out and see if they can get it to work, the address is :
37W450 IL Route 72, Dundee, Illinois 60118
