I just received my copy of Cataclysm from my local Harvey Norman, (naughty naughty breaking sell time) and I was just wondering wether I have to install anything from the CD or can I just upgrade my account and jump right in at 7?
I'm sure all of the Cataclysm files have already been patched in and I won't need to install anything but I just wanna make sure.
Also, if I do need to install anything from the disc will it delete all my addons and such?
