Okay, we can try a few things.
- Open the game's folder. Navigate to "bin/Fonts", right-click on the "Formal436 BT.ttf"-Fontfile and select "Install". This should install the game's font on your system.
- Then go up one directory to "bin" and start the Game.exe in that directory.
If that works you'll propably have to always start the game through the bin/Game.exe. I'm very sorry for the inconvenience and I hope this solves your problem!
