Union Admin

Hello! My issue pertains to running Union Admin or any file for that matter that connects to the Union Server. I have set up the Union Server on Windows XP. I installed it into my "C:\Program Files\xampp" directory and have it's policy.xml file set to allow all connections. I have placed the UnionAdmin.swf into my "C:\Program Files\xampp/htdocs" directory so that I can load it from localhost. The issue is when I do load it or any other file from localhost or 127.0.0.1 and they try to connect to my Union Server, I receive a halt/disconnect because of a sandbox violation (It states I don't have persmission from localhost/127.0.0.1). I have tried to place a crossdomain.xml file in the xampp, union and the htdocs directories and that did not resolve the issue. Does anyone know why I can't connect even though they are in the same directory? When I try to make a connection via Union Admin, I have tried localhost and 127.0.0.1 as my host and 9110 as my port. Any help on this issue would be greatly appreciated. Thanks
