Hello,

?

I have JMRI connected to my layout with an NCE USB interface. I have software for the interface using COMM4. Since originally installing JMRI, I updated my computer to Windows 10. When I try to start DecoderPro I get this message in a window: “Unable to create connection "NCE2" (N2). ?Serial port COM4 is in use. Unable to run startup actions due to earlier failures.” I believe I have deleted “NCE2(N2). When I ignore message and continue to DecoderPro and select a locomotive the following error message appears at bottom of screen: “Service mode program NCE is offline and Operator mode program NCE is offline”. I spoke with Ed at NCE today and he said problem is with JMRI and Windows 10.

What do I do? When I had Windows 7 Pro, I was able to set up 5 locomotives.

Thank you,
