Request Not Authorized or Over Querylimit' - Googlelocationservice

Question

Follows code:

var locationService = new GoogleLocationService();
var point = locationService.GetLatLongFromAddress("Rua Osasco - Amador Bueno, Itapevi - SP, Brasil");

Error:

System.Net.Webexception: 'Request Not Authorized or Over Querylimit'

This above error occurs in the second row if I return the breakpoint on the line : var locationService = new GoogleLocationService(); and then go all the way, it’s okay. I don’t know why you’re generating this problem. Any solution ?
