Minesweeper will not open

I upgraded to Windows 7 from Windows Vista a few days ago. Today, I tried to play minesweeper and it will not work. I looks like it tries to open it but nothing happens. It will open all other microsoft games on the computer, just not minesweeper. I watched the process in my task manager and I can see it trying to open. Two new processes come on when I try to open it, "Minesweeper: executable for minesweeper" and "werfault.exe:windows error reporting." I looked in the event viewer and copied what was wrote in there. I'm not sure if this can help anyone figure out what the cause is or not.
