^It took a long time for my daughter's verification email to arrive, and when she clicked on the link to validate it, she got a page saying that the registration wasn't working and she'd have to create another account (which she couldn't do, obviously). So she went to pottermore.com and put in her username and password to sign in and it worked. Worth a shot for you to try it too. (If you don't remember your username or password are, you can ask the site to email them to you.)
