Thanks for feedback!
Compatibility with Vampire is kinda tricky for us since we don't have such hardware, but we have some Ideas why this isn't working for you.
I assume that you're running the game from Coffin OS by extracting the zip. Could you try to run it by booting from floppy drive witch caches disabled in early startup menu? Also, we'll be glad for a feedback if it worked or not - it will allow us to narrow our search for this bug.
