When your save game name isn't the same as your DB folder name, CMH has a hard time auto-adding to the right folder. So therefore you need to manually add the first file to the right DB folder. A simple copy and paste the game file from your game directory into the right DB folder and then start up CMH and it should see it and create the game for you.
To avoid this use similar names for your games/DB folder. Like if we were to play each other, Id name our save game "stardekk vs Meat 001" and then also name the DB folder "stardekk vs Meat" and CMH takes care of the rest.
