VMM cannot be programed

New VMM3120 power was interrupted during auto-program. Now power and net1 leds flash together at 1/2 second interval.  VMM cannot be programmed with DLA; Download Application does not find this VMM.  In VMM software interface, Query J1939 finds and identifies this and all other VMMs in the system, but Query VMMs does not find this one.  I'm trying to figure out how to get it back to its original state or to any state where it can be reprogrammed.
