I recently opened Windows Live Messenger, and the addon that I have installed, Messenger Discovery said an update was required. I clicked yes to this, the update started, but didnt install correctly. This also meant that windows live messnger would stop working whenever i opened it. I uninstalled both messenger and discovery, but now when i try to reinstall windows live package, all i ever get is an unknown error saying, "programs could not be downloaded". This is really starting to frustate me now as there seems to be no way to re-download the programs. Any help??
