As I said in that thread I'm not having any issue with the current CN maps in MapSource.
Well it'd be nice if someone would post, in that thread, an exact location (i.e. coordinates) or a gdb/gpx file containing a route that results in a crash.
Evidently, and I just looked at the thread, that is too hard.
What happens if you just open the GDB file I attached to the post?
