I don't think that CBM is a problem. It is likely distinct pretender choices that cause the game to crash, if the CBM modes are incompatible. I think the problem is the map.

Ask the question on the maps forum, and someone can likely help you get it set up. Provide an attachement of the map you are trying to use, and hopefully someone else will try it and tell you what is wrong.
