title: ReferenceError: Error #1065: Variable JSON is not defined
body: <p>I'm about to explode trying to figure out how to fix this so before I do so maybe you could help me? I'm developing an game under flash player 11 in flash builder 4.5.1.21328 and I wanted to play around with the new stuff, for example, the native JSON support, but when I try to launch the application in Flash Builder I get this:</p>
  
  <pre><code>ReferenceError: Error #1065: Variable JSON is not defined.
  </code></pre>
  
  <p>I've added compiler argument: -swf-version=13, I've downloaded the flash player 11 playerglobal.swc and placed where it should be in flash builder directory, so I'm stuck now.. How to fix this annoying thing and enable flash player 11 in flash builder?</p>
  
  <p>When I use the 'Generate HTML wrapper file' option for my project and run the application in browser, it runs smoothly.</p>
