Terranova EXP for BHD... haven't heard that name in a long time. I do remember it installing differently than other BHD mods, as it was made before Nova released their mod tools (if I recall correctly), so can't say I'm surprised you're having some issues.
You could always ask one of the original members over at their forums.

I don't think there's been a post since 2015, but loa would probably get a notification if you posted. Last I checked, he is still bumping around and modding newer games
