how can I configure client.xml in the free desktop client

[shahramsedehi]

Also, how can I configure client.xml in the free sample desktop client at
(http../www.123flashchat.com/download/123flashchat_client.zip
I want our site user to be able to chat from their desktop.
I don't need customization, just I want to configure it so it will show only the rooms for our account and not other ones.

My server is hosted by 123flashchat.com.
I looked into the source code for my account at http../host120.123flashchat.com/vipmeetinghouse/ and and tried different server names from that code too which did not work.
Inside the zip file I found these two xml files and I tried many different server names , but non of them worked.

</FCClient>

<Connection>
<primaryServer host="www.host120.123flashchat.com" port="51127" />
<secondaryServer host="*" port="51128" enable="false" />
<httpServer host="*" port="35555" enable="true"/>
</Connection>

<group value="default" />

</FCClient>

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

I think that may need to be customized.
