I had the same issue after just purchasing the BN-2T. CTD each time I tried to load after successfully activating the a/c. I went through the process of trial and error removing plugins to see which was the culprit. Lo and behold, it was the X-Aviation plugin. I removed it and no more ctd when loading the BN-2T. Hopefully they can fix this as I'm sure the X-Aviation plugin is considered necessary for perhaps some of my other planes.
