After one of the recent updates to Launchbox, when I tried to launch an Atari ST game, it asked me to point to my TOS.IMG file for some reason; everything had been working before, so I'm not sure why. Anyway, I pointed to it, and then nothing would happen when I would try to launch a game. I thought maybe the TOS.IMG file might be corrupted, so I found another one, installed it, pointed to it again, and the same thing is happening - nothing happens when I try to launch an Atari ST game. How can I fix this?
