Critical Error 3

[Badams66]

Ok, as everyone whose using MSN 6, you already know that you can play games! Well i can play all of them except 1, and thats my favorite 1.....Minesweeper Flags...ever since i cleaned out my registry it says critical error 3, did i delete something i shouldn't have...i don't think i did but it never had problems before! Has anyone else had this problem? Im really lost here and open to any suggestions!
