title: Attempt to scrape a table gives me error for failing to load HTML table
body: <p>I'm getting the error "failed to load external entity" when trying to scrape using readHTMLTable from the XML package in R. See below for the specific code I'm using:</p>
  
  <pre><code>qb_fp &lt;- readHTMLTable("http://www.fantasypros.com/nfl/projections/qb.php", stringsAsFactors = FALSE)
  </code></pre>
  
  <p>Any reason why this wouldn't be working? </p>
