"trouble" with unattended win xp with sp2

[Sesshoumaru]

i made a slipstreamed win XP cd with sp2.

i used nlite this time (back then when i made one with sp1 i had to do it myself)

if i use nlite to make it unattended (i click on unattended suport, and them choose some options, unattended mode it "provide deffault"), after loading the first files in the text only portion of the setup, it stays in "setup is loading windows" .

what could be wrong ?
