My dealer told me that this was not to be done as it was something of a legal issue with RailPro and it was protected by them for legal reasons, which he did not go into. Now I have no reason to do this, so I just blew it off as something I wouldn't want to do anyway. I would think that when going into RailPro Assistant on line there system might detect these other downloads, but me not being a tech guy I wouldn't know what and can't be done. All being said, good luck.
