When I try to access my account on my friends computer, whether I use my email, my user name, use the correct password,it keeps coming back "hello stranger". I finally set up an account in her name for her computer and email address. Same result. Even though her account was set up and did work for awhile, now it won't let her login whether she uses her user name or her email. She has a fairly new macbook so I don't think it's the computer. Any suggestions?
