i agree with wide boy and think that ur original error message is the one loads of us got since windows released a "update"....quite rightly much up is a better word for it.
The reason i reccomended a system restore is to solve the problem of u deleing what u deleted after u recived the erroe message, then i said for u to post the error to make sure i was giving u the correct link to update....if u are getting the problem aload of us have the link provided by hocky in this post
