Help with Update-Help!

I have just upgraded to the latest version of Powershell 3, but my Update-Help won't work.  I am running this in an elevated Admin prompt.  This is the error message I get:

PS C:\scripts> Update-Help
Update-Help : Failed to update Help for the module(s) 'Microsoft.PowerShell.Management, Microsoft.PowerShell.Utility,
CimCmdlets, ISE, Microsoft.PowerShell.Diagnostics, Microsoft.PowerShell.Host, Microsoft.PowerShell.Security,
Microsoft.WSMan.Management, PSScheduledJob, PSWorkflow, PSWorkflowUtility, Microsoft.PowerShell.Core' with UI
culture(s) {en-US} : Unable to connect to Help content. Make sure the server is available and then try the command
again.
At line:1 char:1
+ Update-Help
+ ~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (:) [Update-Help], Exception
    + FullyQualifiedErrorId : UnableToConnect,Microsoft.PowerShell.Commands.UpdateHelpCommand

Does anyone have any ideas.  By the way, my culture is en-ZA, but I've tried -UICulture with this argument, as well as en-US, and I've tried using -Force.
