Hi Barry, please try the updated one from here: http://moi3d.com/forum/messages.php?webtag=MOI&msg=5124.2

Use the one that says that it's been updated to work on OSX even if you're on Windows - that one was updated to use MoI's built in functions for reading and writing to text files instead of the ActiveX FileSystemObject which won't work with MoI v4 anymore.
