Well, I did execute logs.sql, so I don't know why it's popping up with that. The inter_athena.conf is edited too, at least in tems of port number and user name/pass. IPs are still 127.0.0.1 since, again, testing...
EDIT AGAIN. However, despite the above (though still how to fix it I don't know...), I've gotten past the authentication issue, but when I make a character and try to log in I get "Disconnecting session #3 with unknown packet version", so I'm not sure what I need to edit to fix that exactly.
I WOULD also like to figure out precisely why I have this Korean + gibberish config window that's now locked my window size and pops up with some errors of its own, as well, too. I can't get any sound or sound effects from it...
