This is a new one. I recently installed a 73100 board in an Atlas SD50 and successfully uploaded sound file 73850 in it. It runs and sounds fine but, when I return the loco to the LokProgrammer programming track and click on "modify settings of an ESU decoder" I get an error message that says "Decoder version 4.17. 9249 is not supported. Please check for software updates". I've hit "update decoder firmware" and still get the error message (updating deletes the sound file, BTW). I've looked for new versions of the LP software but it says mine is the latest version (4.7.0). I have not installed any chokes or keep-alives in with the decoder. I also have several other 73100's installed in various locos and do not get this error message. Ideas?
