The eddm_aerosoft.pye file should not cause a conflict to another EDDM scenery, because it's only used if the AFCAD in use is named AF2_eddm_2010.bgl, that is the Aerosoft .BGL so, if you see conflicts caused by this file, it's because you haven't properly removed the Aerosoft scenery, so GSX is still using the AF2_eddm_2010 file.
