Windows XP file & settings wizard

Tried to migrate data using the File And Settings Transfer Wizard (FAST) on 98 machine but the software kept failing when it came to import the data saying that it could not find the required data necessary. After running Windows Update on the machine (which had *loads* of updates necessary) the same settings worked ok after a new wizard disk was created and run on the machine. Apparently one of the patches to XP solves certain bugs and issues including FAST ones.
