Air update framework issue

Hi,

Im working on integrating the air update framework on an existing flex app.

The problem I'm facing is that the air update framework ui window shows blank, with a (default blue?) background.

There is no interaction, the only thing I can do is to close the window.

On the flex console I can see the traces from the framework, in which it states that there is an update:

UPDATER: [UpdateEvent (type=initialized)]

UPDATER: [StatusUpdateEvent (type=updateStatus available=true version=0.0.1 details=,Latest release of the test updater app )]

My config file for the updater is:

<?xml version="1.0" encoding="utf-8"?>

<configuration xmlns="http://ns.adobe.com/air/framework/update/configuration/1.0">

  <url>http://www.mysite.com/airupdater/update.xml</url>

   <delay>1</delay>

   <defaultUI>

       <dialog name="checkForUpdate" visible="false" />

       <dialog name="downloadUpdate" visible="true" />

       <dialog name="downloadProgress" visible="true" />

       <dialog name="installUpdate" visible="true" />

   </defaultUI>

</configuration>

Then, the update.xml:
