Virtual Patient-some things that maybe causing the problem?
1.Security and Content Settings in IE.
2.Verify that IE is configured to use SSL 2.0 and SSL 3.0.
3.In iuident.txt go down to:

[IUServerURLs] make sure this is in their:
ServerCount=2
Server1="http://v4.windowsupdate.microsoft.com/"
Server2="http://a248.e.akamai.net/

Look and see, if not put those in it just the way I have them.
