Installation of game worked out just fine. Played game for about 4 hours after I installed it. Again no problems. This morning when I went to open the game I received the following error message: "Failed To Initialize Client - Unable To Load Game Resources". Did a disk scan and defragged. Same error message. Tried to open game up directly off disk 5. Same error message. System does meet game specs. Don't really want to uninstall and reinstall as I don't want to play the levels over again. Any thoughts?
