Update 25.5.5.15 downloaded onto Update 25.5.5.14 on XP

I have Win XP SP3 and downloaded update 22.5.5.14 via Live Update before it was pulled. Update 22.5.5.15 has now downloaded via Live Update which I thought would correct it.  However the Norton interfaces that appeared after startup were largely blank with no "X" to close anything anywhere and graphics missing.  I tried restarting again hoping it would improve but it didn't. I was only able to minimise it and click "close" from the taskbar.  I then used the Norton Remove and Reinstall tool which seems to have produced the normal NIS interfaces again but this took 45 minutes to perform.  At one stage I wondered if RnR was faulty because Norton Remove and Reinstall used to take a fraction of that time.
