Windows Update Error. Urgent. Help.

[emmynem_2005]

I have genuine Microsoft Windows XP Professional. I updated it to Service Pack 3. Now when I try to update windows, everytime it asks me to install the WGa component. I have installed it like 5 times. and when I search, then it gives me SP3 Install of 66.7 MB. But i already have that, hence its giving me an error and I cant even install a single update.
I have validated my copy at the Microsoft Genuine Software website. It's a success.
Please help.....
