There is one pc...neither of us can login on it from any account. we can both login on lumiya. I even tried creating a brand new account and still got that same error. I went to my sisters down the street and was able to login on my account. So if anything, it would be my ip or actual machine that is disallowed. SL still on my Exceptions List on Windows firewall, there have been no changes to my pc. I was away a week tending to my terminally ill sister in another state...all i wanted to do was play on SL on my "break" from providing care and came home to this problem.
