This happen after the ff14 update. crashed and say invlaid account, no email recieve for pw change, did a pw recovery and new pw also get same error.
try logging in from the ffxiv launcher not the minion launcher and see if u can log in.
invalid account can be acouple things, it could be that it cannot connect to the ffxiv authentication server. make sure you also do not have a ffxiv launcher open
if this is open then the bot cannot access the ffxiv authentication.
Whenever I get a crash, the bot reverts to old settings (including expired keys). Check that your keys are up to date maybe?
