error starting games via start games file association

Hi,
when I want to play Microsft Games I click on Start and then Games. I then get a window with the Microsft games.
However, when I try to run any game at all in that window I get the following error message in a popup:
X C:\ProgramData\Microsoft\Windows\GameExplorer\{any SID of a game}
"This file does not have a program associated with it for performing this action; Create an association in the folder options control panel"
I have tried to restore to a previous version via the properties sheet of this folder, but it did not work.
Please help!
regards,
Robert
