The same thing is occurring for me, as well, when trying to load Kong on Internet Explorer. I am running Windows 7 OS. IE 9.0.8112.16421, Update Version 9.0.12 (KB2761465). I have not deleted IE history or cookies and all my Flash save files are present in their folder (C:\Users\…\AppData\Roaming\Macromedia\Flash Player\#SharedObjects\…). Note: Firefox is working fine.
