hi all I trying to use jmri with a prodigy 2 but I keep getting strange things happening on start up it says com3 is in use on the layout editor it only shows internal turnout settings so I cant edit points to control them I bought a sprog 2 recently to program with decpder pro as the prodigy kept giving false reading when trying to  identify a loco on the programming track I'm wondering if the prodigy is not really compatible with jmri any advice would be helpful please
