title: Protobuf-dt 1.4.3 not opening in eclipse 4.2 Juno
body: <p>I tried to use the protobuf-dt plugin, and I managed to install it using the "Install new software menu", but the plugin is not displayed when I open my .proto files.</p>
  
  <p>The plugin is listed under the "Installed Software" tab in the "Eclipse SDK Installation Details" as the following entry:</p>
  
  <pre><code>Protocol Buffer Editor  1.4.3.201307151341 com.google.eclipse.protobuf.feature.group    Google, Inc.
  </code></pre>
  
  <p>Software update site: <a href="http://protobuf-dt.googlecode.com/git/update-site" rel="nofollow">http://protobuf-dt.googlecode.com/git/update-site</a></p>
  
  <p>Eclipse version: 4.2.2</p>
  
  <p>Does someone know what might be the problem here?</p>
