Well, back home I usually play without having to edit anything, the client works perfectly. However, this does not work.
I edited the run.bat and discovered that the path to the javaw was different, so I edited it and it worked, the game loads, and logs should appear ... but when the lobby with the characters the game crashes and a message keeps popping up has already connected when I try to enter again.
Only here at work that happens, I found it super weird, I did several tests and could not find a solution.
