title: Installing natural language toolkit data
body: <p>I have problem with installing natural language toolkit for python 2.7. I have NLTK already installed and now i am trying to install necessary data.</p>
  
  <p>I type into shell:</p>
  
  <pre><code>import nltk
  nltk.download()
  </code></pre>
  
  <p>NLTK downloader appears (TKinter window). I choose to download all packages and start downloading. Everything goes well. Until i get message "error with downlaoded zip file" and process stops.</p>
  
  <p>I am using windows 7 and 64-bit python 2.7.</p>
  
  <p>Please help</p>
