title: Looking for download of previous version (v1.3.1) of Mule Studio
body: <p>I recently got added to a project team which is using the following version of Mule Studio:</p>
  
  <blockquote>
    <p>Version 1.3.1 Build 201209041237 </p>
  </blockquote>
  
  <p>I would like to download and install this version on my Mac but I cannot find the download location anywhere. Can someone tell me where I can find it? 
  I can of course download 3.4 but that only works with Mule ESB 3.4 and we cannot upgrade all our Mule instances just because a new developer is added to the team. </p>
