Can't get ML to appear

[JW]

I have created a barebones media library container, but can't get it to show up. Winamp THINKS it's visible, because there's a checkmark next to it on the menu.

PHP Code:

<elements>
  <bitmap id="ml.bg" file="player/mlbg.png" gammagroup="Backgrounds"/>
</elements>

<groupdef id="ml.group" name="MLGroup">
  <layer id="ml.bg"
    x="0" y="0"
    w="200" h="200"
    ghost="1"
    image="ml.bg"
  />
  <component
    x="0" y="0"
    w="200" h="200"
    noshowcmdbar="0"
    autoopen="1"
    autoclose="0"
    param="guid:{6B0EDF80-C9A5-11D3-9F26-00C04F39FFC6}"
  />
</groupdef>

<container id="mlib" name="Media Library" dynamic="1" component="guid:{6B0EDF80-C9A5-11D3-9F26-00C04F39FFC6}" default_visible="1">
  <layout id="mlcontent" name="Media Library Content" background="ml.bg" droptarget="pldr" default_visible="1">
    <group id="ml.group" x="0" y="0" w="200" h="200" />
  </layout>
</container> 


I created a playlist just like it that works perfectly. Is there anything more I need to get it to show up?
