If you already have an active account you don't have to write your key when reinstalling the game, when you get to that screen about creating a new account there is the option to log into an existing one where just username and password is required. This information is not stored on the registry but on the player profile file (USR file), if you installed a new OS you probably have a new OS username, try moving the games application data folder from the old OS username to the new.
