Lost Performance Score
 

When I first had my Vista Home Premium laptop, I was able to access
Performance Information Tools via the Control Panel and the page would show
the "Rate and improve your computers performance" at the top with the
performance details and score below together with the "Update my score"
button at the bottom.
Suddenly, all the performance details and score, together with the "Update
my score" button, have disappeared leaving only the Rate & Improve title
highlighted in blue which does not function when clicked.
Can Anyone please tell me how I can get the performance score details back?
