Where did "My Network Places" and "Shared Documents" go?

-I recently discovered my copy of XP was illegal, so I ordered the WGA-kit.
After installing it I realized all my music (My whole record collection) and
all shared pictures and videos were gone. I had them put in shared documents
and shared the shared documents folder on my small home network. Are all
files deleted? It was 13 Gb or so containing music, photos and videos. I've
tried different undelete programs, and managed to recover files and settings
from personal user accounts, but everything from the All Users account and
My Network Places seems to be gone. Are the files stored in any hidden folder
or so? Is there any way I can recover the files?

Yes, I know I should have backuped or moved the files before installing XP,
but I've done these kind of operations many times before, and always been
able to find stuff from older installations. But not this time. Any
suggestions? -Please?
