CrossDomain Problem not found

I have a game on web player and the error "WWW Error: Rejected because no crossdomain.xml policy file was found" keeps coming up. Even though the game and the file I'm accessing is hosted on the same domain, I have changed the www security emulation to the domain the game is being hosted. The crossdomain.xml is written as followed.

 <?xml version="1.0"?>
 <cross-domain-policy>
 <allow-access-from domain="*"/>
 </cross-domain-policy>

Any advice on how to fix the problem?
