Ok, so I just uploaded a minor patch. It should add support for loading older BRFs. This should make the porting process a little easier for some of you. Note that it will still only save in 0.950 format, so you cannot really use it for creating mods for older versions of M&B.
Also note that this is again a very quick fix. At the moment I can only manage to spend maybe an hour or 2 every couple of weeks working on M&B projects, and although some people may not realize it, it takes quite a lot of time to keep something like BRFEdit up to date. Especially when you consider that I have no source code to know what the BRF files contain.
It is also kind of unfortunate that I got half way through re writing most of the rendering engine, and then ran out of time. So yes, there are lots of bugs, and some features that don't work at all, and I apologize for the delay in getting things sorted out.
