Hi Steve,
Thanks for the kind feedback. If you liked the native version, you are sure to like the Unity version which is in development

Can you check whether the default campaign data got installed to the folder:
C:\ProgramData\The Midnight Trilogy\campaigns\lom\scenarios\default
There should be three files in there:
newgame._db
newgame._es
newgame._mp
If they are present, a few other things to try:
- Run the game as Administrator, see if that helps
- Uninstall and re-install the game but this time selecting a different directory for the campaign data
Many thanks
