When I only have CM selected as the extra book, and I click 'main character' in the step to choose what I'm creating, I get a black screen. I didn't do full testing to see under what conditions it replicates, but as far as I can tell, it only happens when just the Core and CM are selected, and no other books.
Good catch. If you don't have either the Klingon book or the Player's Guide, the "type of character" screen is skipped, and there's some essential set-up that happens on that screen. I'll get a fix today.
