Have you deleted your cookies and temporary Internet files online and off? If you have recently downloaded any software, un-install it (keep it on your computer because this might not be the cause of your problem) and then try the game again. Was there a date where you could actually get onto the game without receiving that message? If there was an earlier date you could do a system restore and this effectively should make it to how it was on the restored date. If you need help with the system restore just ask. Disable any AD stopping software you might have, this type of software does and will interfere with FlyOrDie games.
Thanks,
