SharePoint 2013 March Update Installation Error: Failed to install application content files

Hi,

I've been trying to install SharePoint 2013 March Update. After installing when I ran the configuration wizard, I get the following error:

Task applicationcontent has failed with an unknown exception
Exception: System.NullReferenceException: Object reference not set to an instance of an object.
   at Microsoft.SharePoint.Administration.SPAspConfigurationFile.ApplyActionToXmlDocument(XmlDocument xdAction, XmlDocument xd, String sourceFileName, SupportedXmlDocutmentActions supportedActions)
   at Microsoft.SharePoint.Administration.SPAspConfigurationFile.MergeWebConfig(XmlDocument xdWebConfig, String fileMask)
   at Microsoft.SharePoint.Administration.SPWebService.ApplyApplicationContentToLocalServer()
   at Microsoft.SharePoint.PostSetupConfiguration.ApplicationContentTask.Run()
   at Microsoft.SharePoint.PostSetupConfiguration.TaskThread.ExecuteTask()

Has anyone found the issue?

Thanks,
