Re: WoW problem... with my sincere apologies
go to your Blizzard account management screen and download the install client. the 'battlechest' as you refer to it is just a bundled version, right? basically the client download (or any wrath of the lich king dvd) will do the full install for you without the fuss of dealing with multiple versions.
remember, all of your information is basically on their servers. you simply have a library housed locally; ie. even if you only have BC youre still on patch 3.3.3 . anyway, run the installer client from Blizzard and it will download about 7.5 gigs and install them, then it will run updater and patch you to current (if you have problems during patching you might look into downloading the patches individually). but for installation ditch the battle chest cd as long as you still have your subscription.
