By the time you load up XP on any older pc you have lying around and go for an update you probably would be wasting your time at this point. By now Grisoft has been informed well before the article came out with complaints. "Hey what's going on?" Grrr... :mad:
I can imagine they pulled that off the server fast once they heard about it. But for anyone worried since this seems to effect XP more then Vista simply copy the user32.dll file onto a floppy if you have on or another drive in case the original is removed where you can use a live distro to see the replacement copied back if you are not already dual booting with another OS(Vista, Linux).
