Step 4:- If you was able to play the game before, but it has now stopped working without doing anything to your PC, perform a System Restore.
== System Restore is a tool from Microsoft that allows a user to roll back any system updates that was performed and set the system back into the mode it was when a program last worked as intended. If a user used to be able to play a game, but at a point the game stopped working, performing a System Restore is the quickest way possible to get the player back in game.
== For more information about System Restore, Microsoft has provided a good guide that you can see on this article:- http://windows.microsoft.com/en-ie/windows/system-restore-faq
