The easiest way would be to use our 'Reset Game' button. This will remove the game record & all profiles for the game, re-detect the game and put the profile back with factory defaults.
Alternatively, if you have a lot of profiles that you really want to keep for the game in question, you could just delete the game record, then Auto-Discover from the Sim Commander main screen:
Doing so will cause Sim Commander to find and create the game record for you correctly. You would then need to manually assign the newly created game record to your profiles, which at that point have no game record assigned to them because you deleted the game record that was assigned to them.
With either approach, what we're really doing is letting Sim Commander detect and create the game records.
