When I try to update my 10.7.3 OS X software I get the following message: The update "Mac OS X combined" can't be saved because you are not connected to the internet". Well, the problem is I am connected to the internet. While the software is being downloaded (they show it will take 3 hours) I am surfing around the net. It quits on the download time after about 30 minutes or less & then the error message appears. I need need help! John H.
