The Chess game appears to be loading (or connecting) because it does not connect to an ElectroServer.
According to instructions, you have to download and install the ElectroServer and then edit the flash code in the Chess client to point to your ElectroServer.

After some installing and investigating, we installed ElectroServer 4 and Chess.swf. We also took a look inside Chess.swf and found it pointed to an XML file, ServerSettings.xml. Using the same directory path, we created this file on the server (vB arcade and ES4 on the same server for now) and the file loaded (it seems).
However, we are still hanging at "Connecting ...." in the MX Action Script.
I have asked for a bit of help with ElectroServer, here:
