I'd recommend booklover6's suggestion to use an old/different email address to create a new account just to register your Kobo with. Otherwise you'll end up tearing your hair out in frustration trying to log in with your original email address. I gave up on my original Kobo account and re-registered with another email address, but just recently went round in circles all over again trying to register my Kobo Mini with my most recent Kobo account.
