I think really the only answer is to do a system restore - if you are using XP, go to the start menu, help and support and on that page you will see a list entitled Pick a Task - click on undo changes using System Restore . - you will be shown a calendar and hopefully a point where you tried to load the game - it will take your computer back the point just before you loaded game - you will NOT lose any data or anything like that. I hope that works for you. Maybe then you could ty and reload the game (my son uses it and he loves it!!) Good luck!
