title: Error with Future.js in Meteor Application
body: <p>First post here.</p>
  
  <p>I am working through David Turnbull's book titled <em>Your First Meteor Application</em>, and the app is starting to break after I run the command</p>
  
  <p><code>meteor add accounts-password</code></p>
  
  <p>After running this command, I am getting an error message saying an exception is being thrown at line 245 of future.js.  I removed accounts-password using <code>remove</code>, but am still getting this message.</p>
