Hi Mike, the location of your moi.ini file can be shown from inside MoI by going to Options > General > "Edit .ini file" button. That will pop up a dialog that tells you where the moi.ini file is located.

re:
> So replace moi.int there and all other files on the drive_c ?

Yes I think so. You should find the directories it mentions above like the ui folder inside drive_c/moi/ui
