title: Invalid Request upon trying run in simulator
body: <p>I cannot seem to run anything via iOS simulator in appcelerator today:</p>
  
  <p>STUDIO BUILD: 4.7.0.201607250649</p>
  
  <blockquote>
    <p>SDK :5.4.0 (have tried a few different sdks versions)</p>
  </blockquote>
  
  <p>When trying to run I get:</p>
  
  <blockquote>
    <p>[INFO] : Alloy compiled in 0.65622s [INFO] : Alloy compiler completed successfully [ERROR] : invalid request</p>
  </blockquote>
  
  <p>That was for existing projects...</p>
  
  <p>When I tried a new project I got a message stating:</p>
  
  <p>The project has an invalid/non-platform GUID. and cannot be run. Would yo like to register the app with the platform, updating its GUID?</p>
  
  <p>Upon clicking yes it does nothing to resolve the issue.</p>
