User State Migration Tool

I am trying to use the Microsoft User State Migration Tool (from the WinXP CD) to transfer user settings from Windows98 to their new Windows XP machines. I have not made any changes to the .inf files supplied by Microsoft. When I ran the tool on a Windows2000 machine I had no problems. However; when I ran it on a Win98 machine I have a problem when I login after running the loadstate command on the WinXP machine. Basically, when I try to login it seems to authenticate me, but then it just kicksme right back to the Ctrl+Alt+Del screen. This is the command i used:
scanstate \\\usmt\ /i migapp.inf /i migsys.inf /i miguser.inf /i sysfiles.inf

I then used the default loadstate command.
Any ideas?
Thanks!
