Keep craching down

It worked two times, then it stopped working after I tried the dictionary part. It kept saying "The operation couldn’t be completed. (NSURLErrorDomain error 503.)” evey time I insert a word to have it translate. I removed the app and reinstalled it. I removed preference file. Nothing works. Please fix this for me. I use Macbook Pro 2014 version.
