Installing and patching WOW is a nightmare. Unless temptation is that much hassle I'd leave it there for TWELVE months. The blizz downloader will register as a torrent with most service providers who will automatically halve bandwidth when they detect those programs (or worse) for the duration of the download plus a bit. AND it slows everything down speed wise. Mirrors work well but they also take ages to load, sometimes don't work etc etc.

If you've already done it, you're crazy. The installer should update/replace when you patch, or not be needed if you've not wiped the install yet. And if you've wiped everything for one month. I dunno, wow's site itself maybe? You must be allowed more than one download if you got it that way, or the disk perhaps? Clients don't need key codes, accounts doo. The Cd's are probably in your straightjacket :P (i'd go check, I'm just guessing)
