Could not retrieve the SSL Settings

I imported a configuration from another IIS server, which has SSL enabled.  I can see the SSL certificate within IIS7, but when I try to bind to it in the Default Web Site, SSL settings, I get a the follwoing error window:   "There was an error while performing this operation.  Details: <blank>  Filename: \\?\C:\WIndows\system32\inetsrv\config\applicationHost.config  Error: <blank>".  When I click the 'OK' button, I have a alert "Could not retrieve the SSL settings.".  Any idea what is wrong with the applicationHost.config file??
