Sorry about posting this in the wrong place. My bad.
I would look in to your internet connection. It just may be the culprit here.
I haven't personally has dropped connections using Command Center but maybe 2 times since Command Centers inception. Even then it will download but say it is corrupt or something to that nature.
Next time your ready to update, try resetting your modem, then give it a try.
You can also verify your connection in Task manager through out the download.
I know its tedious but it may shed some light on weather or not its connection related.
I had a bad modem cord a few years ago and had similar issues (not with CCC though).
It drove me crazy until I figured out it was a rolling chair was rolling over the cord that broke the connection.
