I can't replicate this.

Do note in your error output: [nltk_data] service not known.

nltk is known to generate a nltk_data folder in your home directory (or elsewhere? look it up).
For me, this folder was in /Users/lucas/nltk_data

Make sure that you haven't deleted it by accident because that folder is where your corpus data will be saved!
