I have the exact same problem as you are suffering from. All I did was use the WLAN, and LAN driver packs so I could be guaranteed of internet connectivity once loaded, I did not use any sound or other packs. Looking on Ryan's forum earlier today it appears that he removed a hotfix, or something that is causing this. It will be corrected he says in the next update. So for now, it is a pain when it halts at these files, but it does not affect operation of XP.
