As in title. This is very frustrating. I don't have any other information than 1. it works, and then 2. the next time I tried to sign-in it gives me the "Authentication Rejected" error message.
The first time it happened, I was at home and could reboot. Now I am away, and needing to access my home computer, but I can't.
I have read some other forum posts, and it seems other people are having the same issue.
Is there a solution?
