After looking into this a bit I was able to find a good help site. http://support.Microsoft.Com/kb/314060/EN-US/
This site was able to help a number of people with the same problem. Just click on the fix it yourself if you want to. Or you can fix it automatically, my opinion is if you are not a computer person I would not fix it yourself, fix it automatically.
I hope this helps!
