A couple problems I'm having with default Vista games

I've added the Games option to display as a menu for my start menu and
everything worked great for a while. Now though, whenever I attempt to open a
game, say Spider Solitaire or any other Vista default game, it never opens.
The interesting thing is that the games open fine in Game Explorer. The game
links also work if I open them through the Games folder in the All Programs
menu. Is there a way to fix this so I don't have to open Game Explorer
everytime I want to play a game that is only a couple clicks away?

Second, I've noticed one game, Hold Em for Vista, does not open at all. When
I open the game through Game Explorer it just directs me to the saved games
directory (C:\Users\Username\Saved Games). How do I fix this?

Thanks for any help.
