Narrative:
During a ground station computer lock up; the aircraft momentarily received a link from the ground station during the pilot payload station swap. At that point the aircraft left its emergency lost link mission. The aircraft took up a westward heading and exceeded the authorized boundary to the west; when it was realized; the ground data link terminal was turned off and the aircraft returned to the authorized boundary and its emergency mission. Another ground station was used to land the aircraft with no further incident.
