Hi, thanks for the great application. I had a problem while executing the file. Here are the output :
Traceback (most recent call last):
File "retweet.py", line 186, in
retweet()
File "retweet.py", line 58, in retweet
replies = api.GetReplies(since_id=max_status_id)
File "/Users/tajulazharmohdtajulariffin/Mining-the-Social-Web-2nd-Edition/Retweet-master/twitter.py", line 1491, in GetReplies
json = self._FetchUrl(url, parameters=parameters)

Thanks in advance
