Here is the .conf file we use:

listen=1
server=1
daemon=1
maxconnections=100
rpcuser=yourusername
rpcpassword=yourpassword
addnode=54.186.134.64
addnode=23.97.129.104
rpcport=55887
rpcconnect=127.0.0.1

Also remember it should be named "CornerstoneCoin.conf".  Sometimes checking the exact spelling will uncover the problem.
