When I started the download at 4 am it stated it would take 12 hrs to complete.  At 6 I had to get ready to leave for work and it said that it would take 12 hrs to complete.  The speed just kept going down and down.  This was for the content file.  The Carrara file, which is approx. half the size, took only about 5 min.  I hope when I get home the download is compete.
