Translator Engine Google don't translate

Hi, that it twice that I use your plugin and when I use “Google” as translator engine (even with a key), the translation don’t work. So I must use Bing. It’s not a big issue but I don’t understand why. Somebody know this problem ?

Thanks for your response.
