I did read what you said... perhaps it was vaguely put:
Last time I installed SP3 , gettin rid of Vista and installing XP on my system
So then, from your last post, I assume that you replaced vista with SP2.
And THEN upgraded to SP3.
However that was not stated before... and I could reread it many times and come to the same conclusion, so it is not necessarily an error on my part either.
But anyways- am I to assume that after installation of SP2, it was (of course) a clean install, you added pictures, files, etc. and then upgraded to SP3 and found those files missing?
If so that would be most peculiar.
