[Plugin: Codestyling Localization] translate with API Service by Google not working

I have an issue with the translate service by Google. If i press the link it looks like it does nothing except the rotating image.

I installed firebug, and see that there is a response from google with the translated text. But it does not show up in the translation box. I tried all different browsers (Firefox, Chrome and IE), but that doesn’t work either. I don’t get any javascript issues, so i don’t know where to look anymore.
