I can see that this page is translated into English: http://www.sunpropertyrentals.com/en/
I have checked the debug.txt and can see that you have exceeded your Translate API daily usage limits. So you need to wait.
You can also change to Bing which has better translation limits and the translation quality is not any worse. But before trying Bing you need to make sure that your server has PHP Soap Client library installed.
