Problem with reinstalling SP2

[Guest]

Something happened to my Windows XP Home Edition. Before the official SP2
came out, I used to have its bete version installed. But after I uninstalled
the bete version, and tried to install the official version, Windows Auto
Update just can't identify my computer as SP1 and won't show me the update.
Is there any way to resolve this problem? Thanks for any advices.
PS. My current Windows version (Version 5.1 Build 2600.xpsp2.030422-1633 :
Service Pack 1)
PSS. I had lost all SP2 functions after uninstalling the bete version.

You can reinstall the beta, auto update will work and install SP2 over this,
and it will save some download files.
