If you have recently purchased a subscription via a third party or publisher and are not able to login and access your Zinio account or if you are getting the following error message when attempting to login, "Error creating user Uh-oh. A user with the email address you entered already exists. Please try entering a different email address.", this might mean that while your Zinio account has been created, it has yet to be fully verified.
In these cases all you need to do is go to www.zinio.com, on "My Magazines" at the top right corner of the page, select "Sign In", then click on Create an Account, fill in your details and Click on "Sign Up".
Once that is done you will be able to access your Library.
