Hey guys, bringing this topic back from the dead. I originally had the same problem here and followed all the steps above.
When I booted it up however, the launcher cant seem to find the config file because there is no file name jaconfig.cfg. I have the game on steam and have tried starting up the game through both steam and the desktop shortcut (didn't know if that makes a difference). I have started new games saved and quit. I feel like I have tried everything but I cannot get the jaconfig file to appear.
Any suggestions?
