I had this problem too. It seems that the plugin can crash while its compressing the large textures in eve and the astronomers pack. The trick is to only install a few parts of that pack at a time with no other mods then it should work. Just remember to delete the old compressed textures in the plugin dir first.

Seems to break action groups unfortunately, tested on fully stock KSP install, can't select parts to add to a group. Too bad, this mod would have been perfect for sub-assembly manager.
