Im having HUGE problem I went and updated to version 72 and not showing or displaying on my Arcade machine, I even try to do fresh install and still wont show the display 
Can you run attract-console.exe > log.txt
and share the log file so I can debug it? If you can't share it here send an email to paolo.zago@gmail.com
