Enjoyed my time wandering around the exhibition, though there seems to be an issue with text rendering on OS X, as in.. it's invisible for me.
For me it was .wine/drive_c/windows/Fonts, but that was for WINE on Linux: it's a little like having a fake Windows machine running inside your actual computer. I assume on a Mac the equivalent would be actually installing the necessary fonts on your machine. I'm not absolutely certain having never used OS X day-to-day, just hoping I can point you towards some kind of solution.
Do you have those fonts actually installed on your computer (ie. could you use them in documents and such)? I don't think the application is looking for them in any of its own folders, I think it expects them to be installed and available to any software that might be able to use them.
EDIT: According to bloomingbridges having the fonts installed makes no difference. Still, I hope you get it working in the end.
