Go in and do what Norton tells you to do from the page link you posted. After that if you restart and still get error messages, put you XP CD in and reboot. When it asks you to boot from CD hit enter and you'll get a sreen that says something like this:
To setup Windows XP now, press ENTER.
To repair a Windows XP installation using Recovery Console, press R.
To quit Setup without installing Windows XP,
press Press ENTER to set up Windows XP.
On the Windows XP Licensing Agreement screen, press F8 to
agree to the license agreement.
Make sure that your current installation of Windows XP is
selected in the box, and then press R to repair Windows XP.
Follow the instructions on the remaining screens to
reinstall Windows XP. After you repair Windows XP, you may
be required to reactivate your copy of Windows XP.
This should repair or replace the files that are damaged or missing without lossing your other files.
I hope this helps and you should crankup your Zonealarm settings if your on the net because this is not just a pesky bug that deletes files, engage the internet lock in Zonealarm if your away from your computer so nothing gets on line.
Good luck!
