It's telling you that exact message, that your email is banned? I've never heard that one. It's possible that the Meep is already registered (if it's second hand), or that our portal website is having a temporary issue in allowing you to register. We're investigating some portal site issues, so that's a possibility, but it would be helpful to know what email address you are trying to use and the Exact Wording of the message (a screenshot is even better). You may send me a Direct Message here and I can work on this with you, or you can reach me through our Facebook Page (Search for MeepTablet US).
