The problem is that BM: Balack optionally adds a surface for the shattered planet. I'll add proper compatibility later. For now, to play with your modlist you should
1) Start with only BM: Balack and its dependencies
2) Turn off the "Shattered core" startup setting for BM: Balack
3) Add the rest of the mods

Fixed in 1.0.1. Shattered Planet and BM work together by default
