You cant change the names like "Mercury" and "Venus" from server side, because the server is only the numbers that the client use for know what to show. the names pointed in the client side in this file: cabal_msg.enc, for change the values you need to decrypt this file, edit and then encrypt again. when the file is decrypted it looks easy, like this:
<cabal_message>
<version index="1"/>
<nation code="US"/>
<cabal_msg>
<msg id="server1-1" cont="Mercury" />
<msg id="server1-2" cont="Venus" />
<msg id="server1-3" cont="Mars" />
<msg id="server1-4" cont="Jupiter" />
<msg id="server1-5" cont="Saturn" />
<msg id="server1-6" cont="Neptune" />
<msg id="server1-7" cont="Pluto" />
<msg id="server1-8" cont="Leo" />
<msg id="server1-9" cont="Sirius" />
<msg id="server1-10" cont="Draco" />
<msg id="server1-11" cont="RESERVED" />
<msg id="server1-12" cont="RESERVED" />
<msg id="server1-13" cont="RESERVED" />
<msg id="server1-14" cont="RESERVED" />
<msg id="server1-15" cont="RESERVED" />
<msg id="server1-16" cont="RESERVED" />
<msg id="server1-17" cont="RESERVED" />
<msg id="server1-18" cont="RESERVED" />
<msg id="server1-19" cont="RESERVED" />
<msg id="server1-20" cont="RESERVED" />
I hope you know how to decrypt files, because i dont =P
