The only thing I can advise is to make sure your programming track is very clean.? If the track is dirty at all then Decoder Pro might have errors.? I use a programming track and a Sprog 3 to program all of my decoders using Decoder Pro including WOW, Lok Sound and Soundtraxx decoders and rarely experience difficulties.? If I have problems it usually is caused by dirty wheels on the locomotive or a dirty programming track.? The only decoders that I have ever experienced problems programming using Decoder Pro are a couple of locomotives equipped with QSI decoders.
