Just registered for this tool, but trying to use it I get error message: The request returned the following error: Exception from service object: Invalid authorization key: ... I copied & pasted my Google AJAX Search API key when registering. Anyone know why it says its invalid? Have I done something wrong? Have I tried to use the wrong key? The url I've given matches that which google says the key is valid for. Thanks for any help you can give! Ps. the api key I have is a very long strain of random numbers & letters.
