Hello Henry,
I've got the same error that is discussing here.
I have a dedicated APS.LCM with the Visual Difference Service, but it still not working. Comparing and LCMBIAR with the same promotion job in the CMS.
Otherwise, I try to compare VMS against VMS, it connects succesfully, but when I search for an object, it only appears de LCM folder. And as I know, it should shows VMS objects, not the Promotion jobs.
It is so weird. Could you help with that issue?
