Pre-ordered key questions

Hey, not sure if this is the right place to post but im just looking for some quick answers..

If i bought one of the packs and got a key, would that mean i could play the beta straight away?

Also is the key per account or per user? Wondering because im tempted to get a key and play now on my girlfriends computer but im not sure if that would mean i wont be able to play on my computer when i get home.

You get the key you can activate your account right away and play after downloading the client. I am not sure about hopping computers. I would think that you could because you are activating the account online not on a local computer. Does anybody else here know? You could try to PM support and ask them to be sure. If all else fails wait to play on your main computer than try it on the secondary computer.

Yes, you can install and play from as many computers as you like. The beta key activates the account itself.
