Why use the BI.exe? Does it have any real features you want to use? IIRC, the AI is not better, at all (and most of the new formations are buggy or don't work well)
Oh, and I'd rather PM Lethe1 to ask him if he can please send you the map files... it would be rather useless to try to start a map from scratch, and then loose all the progress because the original map gets finished. Besides, you can use another map that's already done, as a place holder, while you wait for Lethe1's map to be ready (and that way, you have a pre-release ready)
