Guild Wars 2

I just installed this app and set up my account to have this but when I just logged into the game, nothing ever had me put in a code.

I’m thinking of getting Windows 8. Can someone that is currently using Windows 8 confirm that GW2 still works the same as it would on a Windows 7 computer? Is the install of the game still the same?

Thanks!

I have also been looking to changing my email address. I don’t use the one that my account is set up on anymore.
