Hi Wade,
This particular warning can also come up if your Account is set to only allow certain users to create/clone an application and they haven't included you on that list. It blocks you from creating a new application or copying an existing application and directs you to the App Manager by default as they are usually builders with those permissions but in this instance you would want to contact your Account Admin to either have the application copied for you by the Account Admin or to have them add you as a users who is authorized to create and clone applications.
