I purchased a Vivofit for myself and purchased a forerunner 220 for my wife. We had separate accounts and somehow they became linked. Now when I go on to sync my vivo fit all my wife's works outs show up. I tried to set an account under 2 different e mail address and they are automatically linked to her account. I am sure it has something to do with using the same computer. All I want is my own account. Can anyone help?
