I got that after I bough at exorbitant but not unbelievably exorbitant price from a well know online tat bazaar. Had to get a refund and go buy another, this time from a Net shop site which was only a very exorbitant price. Took ages to be bothered to reinstall, then it said it couldn't and was going to revert. I guess one needs to boot off the new CD or something. Just can't find the enthusiasm. If MS has been ripped off I don't take too kindly to them bullying me; one can get sick of the whole thing.
You should find it still works with black screen and regular nagging, but as far as I can tell, no updates.
If you can tolerate the messing about you get you can phone MS and ask why and get passed from one person to another and be given different numbers to call, and they'll give you an excuse as to why they are taking it out on you, who is not the criminal.
All very depressing.
