Crossdomain.xml problem

I’m having issues with our crossdomain.xml not being valid as far as the Unity3d web player is concerned, can anyone see what’s wrong with this:

Our policy file’s used successfully for a lot of Flash stuff and just consists of:

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM
"http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">

<cross-domain-policy>
    <site-control permitted-cross-domain-policies="master-only" />
    <allow-access-from domain="*" />
</cross-domain-policy>

Any suggestions?

  1. Create a textfile with your code inside
  2. Rename the textfile to “crossdomain.xml”
  3. Upload it to your domain

Sure its at the right place? ( http://www.yourdomain.com:80/crossdomain.xml )
Unity will not respect nor accept crossdomain.xmls in subfolders and alike nor can you put them on other ports and behind verification
