millipede cannot load c#

As I am following the example package from sawapan, I have problem with the "Shells > 05_ThicknessByStress" grasshopper file.

The c# components have runtime error:

1. Error (CS1705): Assembly 'SawapanStatRhino, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' uses 'RhinoCommon, Version=5.1.30000.12, Culture=neutral, PublicKeyToken=552281e97c755530' which has a higher version than referenced assembly 'RhinoCommon, Version=5.1.30000.5, Culture=neutral, PublicKeyToken=552281e97c755530'

I tried open another example file with c# components but those work fine.

Anyone shares the same problem and know how to solve this?

Thanks!!
