WoW Lich King Install Problem

[Infinatex]

Hey everyone,
I just bought a copy of Wrath of the Lich King expansion today to upgrade my account (I have the battlechest version) and when I go to install it seem to already be installed. Has anyone else encountered this problem?

Yeah, the game is already installed, just put the key onto your account, it'll unlock.

EDIT: And by that I mean your Battle.net account.

you already have the data in your client have done since lich kings release, just go over to northrend from methnel harbor / stormwind harbor (alliance) or outside orgrimmar or undercity (horde)

oh sweet, beats the hell out of another hour long install!

what this guy said, there should be instructions with the game on how to activate your CDkey code thingo on the battle.net or WoW account page
