Game crashes

Have bought all 4 extensions to Democracy 3 on Steam (Mac OS)

Have no third party mods, have tried each of the extension mods separately on, have deleted and redownloaded the game - I cannot start the game.

Here is the mistake for the extremism, for instance:

Failed to find LobbyPower for LegalizeBribery,:/Volumes/DATA/filestore/development/positech/d3/osx/democracy3/code/game/src/SIM_Neuron.cpp 370

Thank you very much in advance for your help.
