I am guessing that your problem is with the startup script Draughts.js. This is what it looks like in the repository:

/* Name: Draughts game
   Original code (c) Ben Chenoweth
   Initial version: March 2011
*/

tmp = function() {
        var Draughts = {
                name: "Draughts",
                title: "Draughts",
                description: "Board game",
                icon: "GAME",
                activate: function () {
                        kbook.autoRunRoot.sandbox._icon = Core.config.compat.NodeKinds.getIcon("GAME",0);
                        kbook.autoRunRoot.sandbox._title = Draughts.title;              
                        kbook.autoRunRoot.sandbox.getSoValue = Core.system.getSoValue;
                        kbook.autoRunRoot.sandbox.hasNumericButtons = Core.config.compat.hasNumericButtons;
                        kbook.autoRunRoot.path = Core.config.addonsPath + "Draughts/draughts.xml";
                        kbook.autoRunRoot.enterIf(kbook.model);
                },
                actions: [{
                        name: "Draughts",
                        group: "Games",
                        icon: "GAME",
                        action: function () {
                                Draughts.activate();
                        }
                }]
        };
        
        Core.addAddon(Draughts);
};
try {
        tmp();
} catch (e) {
        // Core's log
        log.error("in Draughts.js", e);
}

Hopefully your file is different! Change it to the one above, and everything should be fine.

Sincerely,
Ben.
