Are you using a proxy?  If you've recently updated R, you may have told 
it not to use the proxy.  You can test this by running


(which will use a proxy if one is defined in Internet Explorer) and 
repeating the download.file() call.  You can make Internet2 the default 
by putting --internet2 on the command line when you start R.
