Can anyone help with any advice please? I have a new Railking PS3 diesel, and I cannot add this engine tom DCS system. I bought the DCS around 2007-8, and today downloaded software version 4.20 as noted in the operators manual (the download seemed ok, and the remote displays v4.2). When trying to 'add' the loco I just get messages of 'check track' and mostly 'no engine to add' my other PS2 locos work fine, and I can add them etc, but the new loco will not be recognised at all ( it works in conv mode without DCS)
