this is a microsoft problem. if you look here, you will see that a zillion people with S&T have the same issue.
there is a patch from microsoft to fix it, but evidently you have to get it from them and it is time sensitive.
it is an attempt from microsoft to catch illegal pirated copies. if you have a valid copy, you can call microsoft and they will help you install the patch that is required. that seems to fix it for most everyone.
