Berzerker, in order to have the right units and events loaded, you are giong to have to run teh 2194Days.bat first. It is located in teh scenario file, and just choose option 1.
As for the difficulty levels, previously, I was going to leave it like that as teh only levels to choose, but I have since changed it. To play, choose the last Do Not Use level (deity).
Sorry for the confusion.
