First, it should be mentioned that freerouter is more than just an "auto" router. Its "manual" routing is what I use almost exclusively within that program. From time to time I will "select" a single part or even single pad and ask it to auto route that board subset, but all my designs so far have been too complex to get acceptable results with an auto router.
However, let it be known that the manual routing within freerouter is world class, largely because of the "push and shove" feature. And Kicad's routing, auto or manual, is no match for it, in my experienced opinion. You will need to attach your *.DSN file to a support request and post it on the freerouting.net support forum to get help on your issue. The lack of diagnostics within the "freerouter *.DSN loading function" has been complained about before and a feature request has been submitted, to no effect. Dick
