I had problems when the XP SP3 update came along = with ZA, Dlink and my cpu

but now I deny the SP3 update when it asks if I want it and just accept all the other updates.
I do have to turn off my ZA temporarily so the updates will be accepted, but at least I finally got it figured out.
after a lot of frustration , searching and reinstalling 3x before I got it all sorted out..

I finally do proper back ups and have a recovery program and 3 copies of various back up programs LOL on a spare hard drive.
