There is no way the uptating of the updater can ever take that long. The updater is just a few MB in size, so it can hardly take an hour even on a bad dialup line, if we assume that you aren\'t running on an 386 SX 16, which we probably can.
Therefore, there must be something that is blocking almost all traffic from / to your computer. Since it managed to go to 8%, it can\'t be the usual application firewall, that would block everything so you would not get anything regardless of how long you wait.
Usually, when you are uploading something (Bittorrent, for example), this can clog up your upload pipe so that requests and ACKs for the download can\'t cet throught anymore, so maybe it\'s something like that.
Otherwise, this strongly hints at either faulty hardware, probably in the networkling part, and / or misconfiguration of the network.
