Check you userid cast from providerkey and also may need to use / on your single quotes.

/'http://www.website.com/' inside your double quotes for url

Don't forget to mark ANSWER if it helps you.

the syntax I use to get newly registered use's GUIDs is

The SecurityData entity is some group name constants.

protected void createWizard_CreatedUser(object sender, EventArgs e) {
	var pb = ProfileBase.Create(createWizard.UserName, false);
	Roles.AddUserToRole(createWizard.UserName, SecurityData.CMSGroup_Users);

	try {
		MembershipUser usr = Membership.GetUser(createWizard.UserName);
		Guid userID = new Guid(usr.ProviderUserKey.ToString());
		Response.Redirect("./User.aspx?id=" + userID.ToString());
	} catch (Exception ex) {
	}
}
